First of all, thank you for calling Donald Trump an idiot.
On, Korea the situation has been tried and failed for 70 years because North Korea does the same thing over and over again with each new President. Each President has become more and more about tough love until Donald Trump who started off with doubling down on that tough love, then proceeds to suck up to North Korea's leader. Unfortunately, we're just going to have to see how that goes but between Donald Trump not listening to what his Intelligence Agencies and North Korea's usual "We're totally not lying to you until you catch us lying to you" it's probably going to play out like it has for the last 70 years and I have no confidence in an idiot seeing it through.
The Middle East is... a very complicated thing. I cannot possibly go into great detail about it because I don't understand all facets of it. To boil it down to the simplest terms, there are a lot of factions still warring over land, religion, and human rights. And everyone in the First World wants a piece of their pie so they are constantly stuck in a constant state of war.
Again, I don't trust an idiot who think he can fix everything in 4 years, let alone 8. His policy of America First should also apply to these countries. If he wants to cut the cost of aid to countries that are constantly warring with us, fine. He isn't doing that though. He's cutting aid to countries that have been our allies, putting tariffs on our allies, and even if his policy works in the short term, it may have devastating long term effects for decades to come.
I actually agree with Trump on NATO, which makes me think that somebody else is pulling his strings because, again he's an idiot. I would rather THAT person be in charge rather than Donald Trump but he was either too skeezy (More than Donald Trump? YEEEESH!) to run for the office himself, or he didn't want the responsibility. Which is not a GOOD thing to have in a secret leader.
Russia's endgame isn't to invade. Russia will take back the countries that were ex-Soviet Union and we'll do nothing. Russia will, however, watch the situation unfold in Afghanistan, Syria, Venezuela, and so on and continue to paint us as the new Imperialistic Assholes that the Axis Powers was which has been Russia's modus operandi since Putin took office. Thats why no one will return the favor.
And I wouldn't trust Donald Trump with 5.7 billion dollars no matter how you spend it.
