I will go back to the question you posed a couple days ago------------>why no threat of nuclear war, or wars in general under Trump.
Same damn reason there isn't an easily winnable war against a 3rd world country run by a bunch of inbreds in North Korea. Because they view Kim as crazy enough to do it!
Biden has been in government for somewhere around 50 years. All his decisions, his remarks, his votes, his suggestions to Obama when VP, can be seen just by anyone going to the internet. On the internet also, you can see what multiple defense secretary's thought of his stances. You can even see what the President he served under remarked, and it wasn't endearing at all.
Exact opposite with Trump. He was never in government, had no record on votes when there was a crisis, and was totally unpredictable, as unpredictable as the rest of the leaders who run these countries are. He made no qualms about going in to kill terrorists and admitting it after doing so, threatening terrorist leaders with certain death if they didn't toe the line, and addressing issues that for years, no American politician wanted to touch. How many of you remember that multiple cruise missile strike in the middle east he pulled while Xi was sitting at his dinner table at Mara Lago? Do people know that he killed as many Russians in that attack as the people he intended to kill because they were at that site helping them? What do you think Pooty and Xi thought about that!
Trump was an unknown quantity. They had no record, was brash, and they never knew what he might do if they did something.
We can debate if that is/was a good, or bad quality. But either way, it worked. Nobody wanted to play games, because they never could project how Trump was going to play the game.
Bidens own record hamstrings him. They already know what he is going to think before they do what they are going to do, to cause him to think it. That doesn't make him bad, that just makes him totally predictable. You can see by what Pooty did in Ukraine, what he figured Biden would do; so he cut a deal with China and others in advance to lessen the impact he already knew Biden would bring.
How many of you read what General Milly did and said when contacting China? Seems Milly had the same opinion of Trump, doesn't it! By the way, did you know the BRILLIANT Gen Milly said that Kyiv would fall 3 days after the Russians attacked? Man is a genius, isn't he!
So, tell me again if Trump would have been re-elected, who would the blackmailer be on the world stage by use of nuclear weapons by not saying a word. Love or hate the man, Trump had our adversaries afraid of us then, as much as the American public now fear them. To bad with Biden in there, it isn't reciprocal, because if it was, Pootys Ukraine excursion, would have had to wait till the next President, if then!
