I said about Su-35bm as it will be in the front line air defense of Russia for next 15 to 20 years and hopefully of China also and also it is categorized as multi role aircrafts, a good alternative of Mig35 which is less likely to be bought by Russia, as far as I know. Just look on your conflict on 26/11 2011, F16s you can’t use against US and JF17 block 1 wasn’t that capable to face NATO, but if you could have 48 Su35bm, for example, then you might have scored at least 24 of NATO side with sinking their aircraft carrier also, if they make noise, isn’t it? Rest,………. its up to Pakistan ………………..
