I think you're glossing over some extremely important points here.

First, it wasn't that the US ended its presence in Afghanistan, which is something Trump was smart to do. The forever wars were expensive, did not yield any positive results, and had to be ended. However, the way that the Biden Administration ended things was the most half-assed, retarded and embarrassing thing that has happened to the US in decades. Citizens were abandoned, a massive amount of military equipment fell into Taliban hands, and those who had worked with or helped US forces were left to die. It was a travesty of a departure, and the Biden Administration is 100% responsible. Trump was right when he said at the debate, "You never fired anyone. The withdrawal from Afghanistan was a mess and you didn't fire anyone." He's right. Someone should have been fired (but in my opinion, it was the entire damn Administration starting with Biden).

Second, Biden just opened the border. His canard about Congress not passing the law that he wanted that would have memorialized into law letting in up to 5000 illegals a day was political theatre. He had and continues to have the authority under existing laws to stop, deport and control the border. He failed to, and now the US is awash in illegals the way Europe is. At this point we need the National Guard to arrest and deport at least 10 million people, if not more. That's Biden's fault.

As for Russia-Ukraine, it's not just the oppression of Russian speakers in Ukraine:

1. 1990 - US promises not to expand NATO eastwards. Breaks the promise by 1997.
2. 1994 - Budapest Memorandum. Guarantees Ukraine sovereignty in exchange for NEUTRALITY. US unilaterally repudiated it in 2013 to back pro-Western Ukrainians.
3. 1999 - "defensive" alliance NATO attacks Serbia, showing that any "humanitarian" pretext works for attacking other countries.
4. 1999 - US funds Chechen jihadi terrorists while attempting to run a Kosovo-style scenario inside Russia.
5. 2001 - Russia allows US to use its bases in Central Asia to fight Taliban, shares intel.
6. 2003 - US refuses to honor Russian contracts in Iraq and invades illegally,.
7. 2003 - US sponsored coup against Georgian President Shevardnadze, replacing him with Saakashvili.
8. 2004 - US sponsored overturning of Ukrainian election results, upsets the apple cart of neutrality
9. 2005 - Us sponsored coup against Akaev in Kyrgyzstan, replacing him with Bakiev.
10. 2007 - US offers Ukraine, Georgia path to NATO and discuss putting missiles and missile interceptors there, potentially starting to invalidate Russian nuclear deterrent
11. 2007 - US encourages Saakashvili to re-take Abkhazia and South Ossetia to resolve territorial disputes to streamline NATO integration; Russia responds when its UN-sanctioned peacekeepers are attacked and formally recognizes Abkhazia and South Ossetia
12. 2013 - US pulls rug from out of Yanukovich, not letting him sign EU and Russia treaties at the same time
13. 2014 - US sponsored revolution in Ukraine, Russia takes Crimea, Donbass war stopped by Minsk Accords (Merkel later admits that US, Germany, France and Ukraine never intended to implement this agreement, only to give Ukraine "time to rearm and upgrade its military" rather than honor the terms)
14. 2021 - Zelensky publicly repudiates 1994 Budapest Memorandum, publicly raises the possibility of Ukraine becoming a nuclear power again; US also withdraws ignominiously from Afghanistan; combined effect of all these actions convinces Putin that now is the time to act
15. 2022 - Putin reaches tentative agreement about Ukrainian neutrality and disarmament, deal scuttled by insane retard from UK (Johnson); Putin no longer believes ANYTHING the West says

Finally, as for North Korea, I think it was a good thing to try to improve relations with North Korea. The peninsula was farthest from war under Trump and has gone back from that position to a situation that can only be described as "worse than ever".
