you think they should keep their MiG-29s?
In the past, Malaysia's leaders have criticized the F-18 as being good but only useful at airshows since there's a lot of restrictions on its operations (the possibility of using it on Indonesia or Singapore i guess). hence them buying a Russian type (and also because the Russians seem to be willing to take payment through rubber)
They have already retired the MiG-29s from service. The Malaysians were extremely unhappy with them and more so Russian support. Something that does not bode well for the Su-30MKMs.
Re the mentioned "restrictions on its operations", I am curious as to where you are seeing this. I have not seen anything and I doubt it would be easily enforceable if the need arose.
I know the Gen Ackbal, the current Cheif of the RMAF and incidentally a former member of the RMAF MiG-29 Project Team and commander No 19 Sqn, which flew the MiG-29N aircraft, is a keen advocate for the F/A-18D.
