BTW, in case we haven't noticed: The way the air warfare has evolved, getting older fighter jets is not going to cut it for major players. Powerful modern jets are needed between peer powers, powerful integrated air defense system needed, continuous training and assessment needing, satellites, electronic defense... things which Pravin Swaheny has been talking about for years in the context of China+Pakistan vs India conflict.
And I think getting 4+ gen fighter jets is not going to be easy for most countries due to production concerns. I think India is already feeling the pinch despite its deep pockets.
