The Flash-point could be anywhere couldn’t it. Pakistan V India: Pakistan have a ‘First Strike Policy’ and India are under a lot of pressure to change theirs to 'First Strike’ also.
Hot countries produce hot heads.
Iran has the mental capability and clandestine help required to build its own weapons, but the Israel dominated UN won’t let them.
China is getting crazier by the minute, threatening to forcefully suppress the millions of Hong Kong protesters. They’ve already banned bicycles and motorcycles from their cities. Foreigners can’t travel by bus or train. You need a Chinese ID to buy these and a good credit score. Foreigners can never become naturalized Chinese - it’s against their rules and regulations. A country as crazy as this and as anti-Christian, anti-human and with the potential to build undefendable hypersonic weapons; that’s almost certainly where the world will end.
With any sense they’ll destroy Israel while they’re at it.
