This pov may suit a yankee-centric/nato-centric outlook on PLAAF, but certainly not IAF.
Because even if Chinese maal is 50% as good as it is claimed, we are still screwed : we are facing greater than 5:1 odds against if they bring their full AF to bear. 1 Su-30/Rafale for every 5 J-20/J10 ? yeah, we are screwed. We'd be at best, in the position of 'ze germans' in the battle of kursk. With better maal, but so hopelessly outnumbered that quantity wins.
India cannot begin to take the threat of PLAAF lightly without reaching at least 1:2 parity against them in sheer number of active squadrons.
