Answer:

1- In our own view, this war against Ukraine will not lead to WWIII; Russia intends only to force Ukraine to be dependent on Moscow once more. This is the only reason for such a military aggression. Of course, the intention of Ukraine to join the NATO represents an existential threat to Russia. The Russian government is bent on regaining Ukraine under its influence; the USA and the NATO can easily cede their influence in Ukraine.

2- Within WWII, the atomic bombs were 'primitive' and led to the end of WWII, and Germany and Japan were destroyed. The nuclear deterrence of today's world will prevent the rise of WWIII since it may destroy Planet Earth, and end the human race, with nuclear weapons.

3- Hitler was a megalomaniac who desired to control Europe; Vladimir Putin is a fairly reasonable person and not as crazy as Hitler. We do believe that Putin calculates his steps very well to ensure the security of Russia even while risking human losses and economic ones; Putin will always leave his door ajar for negotiations with anyone; negotiations are inevitable in such cases; we do believe that Putin may emerge as a winner within such negotiations.
