Well even in Afghanistan, which to my understanding had extremely low casualty rates the public was still broadly against it,
If you read the paper I linked it would explain why.
Additionally, I was also talking about civilian casualties.
The last time the U.S. fought a war that could potentially injure it, in any shape or form had it lost completely, it considered civilian casualties to secondary to enemy infiltration:
https://en.wikipedia.org/wiki/No_Gun_Ri_massacre That it achieved status quo ante was something of a victory for it though, even if it was more of a victory for the PRC.
Both the left and right can score easy points by saying the military is "woke" or "ruthless" or "murderers" or "soft" depending on their base.
No one would agree with this if a U.S. carrier were sunk in Yokohama harbor except actual America First types. Those viewpoints are always popular until the shooting starts, then they suddenly become not very popular, because the root of the idea is that all tension is misunderstanding rather than true animus. If you forgot about how popular Iraq was, at least until the occupation fatigue took hold, between 60% to 80% of Americans supported the Iraq invasion until the election.
For that matter, consider the lack of a war between the U.S. and USSR. That wasn't because of detente but detente was a symptom.
It seems that the publics' base opinion is that the military is doing something wrong, and it takes Ukraine or a similar event to get most of it to support it.
No, it takes a war where shooting happens and people die, and some flimsy rhetoric to support it.
Stalemates, occupations, and protracted conflicts decrease American incentives to fight, because they convince the U.S. public that the war is not being won, and that a status quo armistice is preferable. What's the worst that could happen? The enemy we weakened pays a higher-than-expected price? Sounds like a victory for the history books, truly.
This is what happened in Korea, what happened in Vietnam, and what is presently happening in Ukraine.
It didn't happen in Iraq or Afghanistan because Iraq is an Iranian ally now and Afghanistan is ruled by the same people from 2001.
Well not necessarily, as I would say that the Americans also have quite a strong revenge drive politically - when somebody takes American citizens hostage, prisoner or what have you abroad it usually gets a big response.
It hasn't yet in Gaza and it barely registered in Iran, outside of a outpouring of prayers during the Superbowl, so it's not very important. The American public is much more intelligent at weighing the ramifications of wars than you seem to imply too. It's not a quasi-instinctual egregore. Again, the paper I linked discusses this.
True, but the military dose seem to be trying to avoid this by overkill the prime example being NGAD
NGAD won't arrive in time, at least if DOD assumptions are correct, and will potentially never be deployed anyway. U.S. intelligence expects a war with the PRC very shortly now, anywhere from as brief as "the next fiscal quarter" to "a hair under 4 years", and it will probably be nasty.
The only major things that might show up are another 200-300 F-35s, maybe a battalion of M1 tanks, potentially a battalion of ERCA guns, limited pre-production quantities of GMLRS-ER and Precision Strike Missile, a handful of LSMs (like 3 or 4), LCAAT assault drones, and a several dozen F-15EX. F-22 and A-10 are both on the chopping block to pay for a couple of these to boot.
It's not nothing, but it's certainly no super fighter, and that's only if America has the maximum amount of time it thinks it has.
You can win with pretty much anything if you spend enough resources on it. I am sure you can win wars with swords even today, you just need a billion under arms and run the other side of ammo and infiltrate all undefended locations.
The point of technology is achieving goals at low cost.
If you can't understand comparative advantage I don't know how to help you.
Would rather not...
why do you need to spend money to have more and better tanks to win, when the opponent doesn't?
...see above.
If tanks is necessary, the opponent will lose if they don't invest in tanks. Why is it that only your side need tanks, and not the other side?
Because some people are good at fighting tanks and other people are good at using tanks.
The existence of FOGM in service in the mid 1980s and the complete lack of countermeasures by armor forces by 2020s suggests to me that most military organizations do not seriously attempt to correctly evaluate reality.
How many American enemies had FOGM? None. You design defenses to defeat enemy weapons, not your own, after all.
Cavalry against machineguns and tanks is what we should expect to happen again, given that governmental organizations have not resulted in superior performance in all other domains of operations.
The last time the U.S. Army fought horses, with tanks and machine guns no less, the horses won.
Force structures with long lead times is very suspect if their countermeasures is evolving at a far faster pace.
FPV drones aren't getting cheaper. Eventually they will be a Javelin missile with CAPS jammers and a propeller on the back vice a venturi.
Surface navies not very relevant in nuclear wars, yes.
Yet they've been relevant for the past 70 years of warfare and will be relevant for decades to come. Curious.
Nuclear wars are no more likely than a massive wall of cheap drones wiping out tank divisions. Israel has lost more troops and tanks to Hamas tunnel commandos with Panzerknackers than it has to Hamas drone pilots dropping hand grenades and flying kamikaze.
If you like old things so much, you should love the return of the Panzerknacker, because it resembles the Imperial Germans' AT weapons!
Tanks can always be relevant if you fight opponents without anti-tank weapons. Any asset can be made to be useful if the opponent does not own or use the counter.
Every opponent America has fought has had horses, magnetic mines, and machine guns, which are proven anti-armor weapons.
FPV drones are only useful because Ukraine sprung them by surprise and the Russians got caught with their pants down. They've stopped being useful as both sides have adapted completely to them, and they are not meaningfully impacting the battlespace much anymore.
Israel has been able to besiege a city in very physical terms and faces a far greater threat to magnetic shaped charge mines than drones.
Tanks as understood in the 1980s is dead against peers. We can watch Russians try to beat trenches with tanks and how much success that has been. The tanks of 1960 - 2020 backed by "nation bankrupting" production numbers could not overcome 1980s defenses.
About as much as Ukraine, except more, actually. Being bankrupt also beats being conquered.
Tanks have to be "rescued" by currently non-existent technology.
Plenty of people have APS for sale.
If you are a upcoming country building an army in 1990,
You would buy Leopard 2s and Marders like everyone else...
The U.S. not having tanks would have made it lose Vietnam, Korea, and Iraq even faster.
there is a good case of not getting any tanks whatsoever. The tanks available are defenseless against ATGM and thus not an advantage over lighter armored vehicles and would be so for another 3 decades. Tank forces are zombies and we don't know if they can be revived again.
Tank forces are more like skeletons and they just need some meat on their bones though?
America and its friends have just spent the past 30 years thinking they would be able to cut into the meat of the armored forces and get away with a dozen tanks lost after fighting 12,000 tanks, all because of Desert Storm, and it was a bad lesson that will take years to correct. C'est la guerre. Whether America has enough tanks in SIAD to handle the next major ground war it gets involved in is an open question. No one knows.
We only know Russia and Ukraine do, and both probably has at least two more wars left in 'em, though.
Tanks are necessary for a very simple reason: infantry cannot protect themselves against bullets and walk at the same time. You will need to fundamentally alter the schema of post-WW1 ground combat. A slightly more annoying anti-tank weapon is not going to do this lol. That just means you need more tanks, maybe making them easier to repair (have more welders?), and perhaps harder to kill.
If infantry evolve into tanks, by putting on bulletproof armor that lets them walk around at 30 kph, we can talk about abandoning tanks. That's the only way you can abandon tanks because they form one of the three points of shock action. The other points are infantrymen and artillery.
There's also nuclear weapons but if you have enough tactical nukes everything is easy. This is why the Army hated Pentomic Divisions: they made it into a push-button force that required no real soldiering or skill.
FPV drones and mortar/grenade quadcopters do something similar for armies without TOW missiles or the ability to do trig.
They're not exactly "game changing" in any real sense.
The Canadians have learned that simple camouflage measures and common sense makes FPV drones far less effective, after all.
They're just another threat to be dealt with in the long line of defense versus offense. As has been the case since the 1990's (at least), the defense is stronger than the offense, and breaking the defense will require more serious integration of robotic systems than "carbon fiber propeller anti-tank grenade". Things that have not been considered yet, or are nascent ideas, so nothing from FCS or its related successors.
All of these nascent ideas, mysteriously enough, still envision tanks as one of, if not the primary, intended use platform.
