Quit seeking Utopia
1 - The War on Drugs is really the Battle with Dangerous Drugs as Part of the War on Crime. It will never be over because you can never stop fighting a mortal enemy that you can never kill. Crime, criminals, dangerous and illegal behavior and substances will always be with us. Because they come from the inherent flaws in every person and the people yet to be. It's tiring and draining but it must always be fought. Can we pick our battles and fight better? Sure, but ending the Battle/War is not an option, it's just a fact of life.
You never get a break from history.
2 - Wars in Shitholes. Sometimes necessary (not often though), should be fought mercilessly (ends faster, achieves feasible end state usually and deters other a-holes thus preventing other wars) against our actual foes in said shithole. Due care should be taken to spare the innocent and deliver aid to those we can help but they are secondary to killing our foes and are often a distraction and enticement to other goals that do not further the interests of the United States. Get in, get done with your mission(s) and get the Hell out. We can't save the world, make people become like us or think that they will see things our way if we just try harder We can win fights, defend/assert our interests and constructively use our other instruments.
Be cautious but not too cautious.
3 - Immigration. It's like salt, just a little bit makes the food better too much ruins it. Greater numbers? No, we have been taking in enormous amounts of immigrants the last 30+ years and we need to take a break, assimilate, tighten our labor market and not believe the delusion that we have magic soil and a values system that overpowers the negative parts of other cultures of people who have been migrating to the US of late and encouraged to retain said cultures and that assimilating is wrong. With the devastation that the COVID virus and subsequent economic shutdowns have caused, adding more workers to the labor market here will not improve the situation for the working, middle or professional classes but it will MASSIVELY help the Investor/Corporate class who will only have more workers competing for a pool of jobs that does not expand proportionately to growth in workers.
Open borders? Nope. The cost of open borders is the dignity and living standards of your working, middle and now professional classes. I don't care what bullshit some pie in the sky academic like Bryan Caplan says will happen and how wonderful it will be. "They" fucked up before, they told us how wonderful NAFTA would be and would not hollow out the core of manufacturing in the US, "they" told us that admitting China to the WTO and giving MFN trading status would eventually cause political and cultural change as they economically grew, still waiting for that, etc.... just two examples of how "they" either don't have a fucking clue about how the world works (people lie, cheat and steal and you must interact with them based on those facts) or they don't care what happens to the masses and are just willing to sell them down the river. Emotional I know, but seeing people push an idea that they themselves will never experience the negative ramifications of while then chiding people without money or privilege about how they just need to get over it makes my blood boil.
People lie, cheat and steal; they always will act accordingly.
