I do not how much of it, but obviously it is more narcissism than any president of the United States is supposed to have, so they can direct their republic to a good future.
If you asked me, Trump with his peace-making speech is not only trying to appeal to people living in other countries or leaders of other nations, the way he uses this speech is order to try tk convince those who are not in favor of using tax money to fund wars, while at home there are people do cannot afford to pay for shelter and suffer in the winters, or those who cannot afford some medicine to take care of themselves.
It is a left wing speech, but twisted to bring people to vote for a man who obviously has nothing to do with left wing policies. It is a good strategy, and will stay as an strategy, since it is obvious Trump won't use that funding to pay for medicine, though.
I dislike Trump as much as the next guy and I think Biden is a much better president and on top of that I think they both should not be the president and someone younger and more fierce should get the job.
However, even I have to admit that Trump was the most anti-war president they had in a long time, everyone else constantly attacked everywhere, even the Nobel Peace prize winner Obama (how the hell did that happened is still beyond me) was bombing kids in Afghanistan while making his speech, that is the corruption of the world, Biden bombed places in the first 100 days of his presidency, he was quick to trigger as well.
Trump is a terrible human, I would not want to be in the same room as him, and he makes me want to vomit whenever he speaks, he is definitely evil to the core, but one good quality about him is that he doesn't want war, and he tries to make peace and that is a VERY important thing in our world, that would definitely be helpful at this moment.
He tried to keep tensions as low as possible with foreign foes of the United States, yes. I believe the most representative moment of his pursue to aliviate tensions with them was when he personally visited the north Korea- south Korea border and Shaked hands with Kim.
Though, his administration was not free of violence or attacks, if I recall correctly he did not care to put an end to the nuclear deal USA had with Iran, and also he fact he was president when an Iranian General was murdered in their own motherland.
He certainly had bad relations with Iran and China. Recall the comercial war between Pekin and Washington? Or how he tried as hard as he could to cancel car factories in Mexico to bring them back to the United States?
Even if he managed to get into the White house again, how he could effectively end aggressions and at the same time not to compromise democracy in Eastern Europe?
