You guys do know nothing is actually sold to ROC, the upgrade of old plane was a compromise needed to keep the island safe from crashing planes! half a dozen people lost their lives to ROCAF fighters falling on them in recent years. the upgrade would still be vastly inferior to J11B/J10B.
all the talk about democracy in this thread is just funny, one may proud of his methods, but the world is determine by capabiities; capabiities determine what you can or cannot do. when US boast itself against USSR, it is because they ARE technically superior, they have the result to prove it as the only nation to set foot on the moon. it is the capability of US that makes it great, if US were backward compared to USSR, would they had been able to win the cold war? it time to talk capabilities and less talk on pride, what good is pride in a system that has trouble reducing poverty and infant mortality?
