Try to convince your kind first about your country capacity to fight two front war before arguing with us, the Pakistanis.
Who is going to stop us from opening 2nd front? JFK is no more who pressurized Ayub khan not to do so back in 62. There are no American leverages in Pakistan anymore who can be used to pressurized Pakistan. Their pawn, Nawaz Shareef is just been booted out of the power.
There will soon be a whole pack of PAF jets flying to China, more then squadron strength at the height of tensions between China in India, to participate in joint exercise with Chinese air force. We have already letting the world know our intentions, with COAS talking about "joint" Pak-China approach to deal with "challanges".
Your bravado and wishful thinking is not going to stop the inevitable.
