There has been a huge change in how the world works since the US elections. We can dislike, disagree, be angry or even approve but it makes no difference, we are where we are and we have to work with that.
At least the world has now had a wake up call, I grew up in a world where ever since world war 2 most countries in the West had some level of a trust alliance, this has now gone completely and I am sure if you ask most people in the west you will find that there is no more trust in America than there is for China or Russia, these countries are largely centered on their own self interests and will change relationships with other countries at a whim if it suits them to do so and they have the right to do this and we have to accept this. I cannot foretell the consequences of the breakdown in trust and relationships between countries but it will not be good.
America has changed so many things so quickly that the rest of the world cannot keep up, it has threatened countries that it will effectively punish them unless they fall in line with what is best for America.
A lot of their changes they have justified as stopping corruption removing inefficiency etc. but what they must realize is that in the case of foreign aid there is corruption in the target countries and there always has been but at least aid was getting through and fewer people perished, now nothing will get through and more people will perish, we should fix the problem not run away from it.
War is a terrible thing, whether in Ukraine, Gaza, Sudan etc. and focus should be on solving these conflicts without self interests of countries providing conditional support rather than doing what will stop the evil consequences of war.
America is correct that it should not be the dominant member in NATO, UN etc. no one country should, we need to level the playing field across these organisations which will mean the rest of the world does have to step up and I think that is now accepted in the West but it will take time and for America to just stop makes the situation almost impossible to resolve.
