There will most definitely be a WWIII, and nuclear weapons will be used in it.
The west should never have intervened in Ukraine, and they should be backing Israel all the way. It seems that American and British politicians have no capacity for long term strategy.
Let me explain my thinking.
Putin wants the return of the Russian Empire. The Ukraine was part and parcel of the Russian Empire for 300 years - they provided their soldiers - the Cossacks.
Nobody was prepared for Russia to waltz into Ukraine - they certainly hadn't prepared a strategy. American intelligence knew about it and tried to warn both Ukraine and Russia. Nobody listened.
What should have happened is that Ukraine should have fought its own battles, and then NATO should have mobilized to all the borders of NATO countries that bordered Russia. That way, Putin wouldn't have been marching into a country that wasn't expecting war. That's a different matter altogether.
As it is, NATO did not do that. They have been stupid. Instead they are draining western capital and western military weapons.
Instead, because both British and American intelligence already know that China is planning on taking Taiwain in 2027/28, they should have been preparing for that.
China has withdrawn all her assets from America, so that sanctions won't help. She is allying with Russia, Iran, and North Korea.
The groundwork for the use of nuclear weapons has already been laid with articles appearing that they are acceptable to use because there won't be a nuclear winter.
And so it goes.
There is another war that is being fought - that of Islam against the west. Nine countries in Africa are currently at war with Jihadi. In Europe, there is a slow realization of assimilation, the taking over of institutions (like the UN and the International Court of Justice).
Nothing can be done to stop it, least of all renaming WWIII 'the mother of all wars and the end of mankind.'
