Honestly, it's only a few countries that can do much to fight things. Canada due to how critical our outputs are for them is one, though we're going to suffer a ton for the ordeal (still worth it IMO), Mexico as well for the same reasons, but the EU and China are basically it for being able to make any notable impact.
In fact, this is actually the best time for China to stand up to the US, because of their imploding economy and population (some estimates put it as low as 400million), they won't have the international power to do much in a decade, like how little influence Russia has now. Not to mention that the EU's been declining for a while now, though they feel like they might be in a resurgence since Russia kicked them in the asses before Trump started backing a dump truck of salt their way.
If this happened just a few years later, the US's relative position in the world would've been twice as strong, so we're lucky it's happening now since the rest of the world has the power to resist effectively. But thanks to Trump, all nations that have strong trade relations with the US will have no choice but to diversify in the fear of Trump doing this sort of stuff for the next four years (or more if he amends the constitution for a third term like what Putin did).
You can only feel for the little guys like the Philippines that gets their entire industries rocked by the US tidal wave when they're so poor that all they can do is beg and hope the US realizes that they're too poor to give Trump anything at all.
I think this is the key thing to remember about those that commit crimes. The penalty is never in their minds when they're considering committing a crime. Either they're presuming that they'll get away scott-free, or that the alternative of not committing the crime is worse than any penalty that could come.
Find me a single person who debates if they'll get two years or five for doing something. Most criminals are completely unaware of what the penalties are in the first place. It could be life for anything worse than shoplifting, and they'll still do it because the penalty was never in their minds in the first place. This is why putting the entire burden of crime prevention on punishments don't work.
Not saying that punishments don't work, but they don't prevent serious crimes in the first place, only minor ones. Punishments only deal with criminals by preventing them from having any opportunities to commit crimes because they're in jail. It's having people be in a good enough position in life that the prospect of ANY jail time enough of a detriment to avoid committing the crime. Having too much to lose is a far better way to prevent crime than guarantee the destruction of a life when you're already destroying their life via other means.
Either way, people who commit violent crimes are never thinking about the punishment before doing so. It's only those that do minor ones like speeding that think about it. Though that said, if you get jail time for speeding, maybe people would actually stop doing 80 in a 40 school zone.
