Our Chinese friends think they will control the world but even Japan is not in better situation, J-20 is a pride weapon, somethink to make the chinese nationalists proud, the reality on a nuclear armed conflict weapons of mass destruction are higher priority because those really weaken the enemy, J-20 has DSI intakes that at the most will boost it to Mach 1.8, it will never reach hypersonic weapons speeds, and it is more expensive that hypersonic weapons, the Tu-160 is far more capable, Russia does not build a stealth bombers because if you add range of Tu-160 plus hypersonic cruise missiles, then you make a Tu-160 as capable as a B-2 or even more, stealth is propaganda, India if really wants to focus on deterrance just needs better ICBMs, or SLBMs and good SAMs and a token force of good fighters, China is like the communist party pure propaganda
