DumbMike, there are many dictatorships around the world, but every country has a right to self-determination. Countries that declare war on others are the problem. (e.g., your heroes: Putin and Trump).
You claim to be a student of history. History has shown that wars nearly always have economic motives, despite the formally stated "pretext" motives.
Trump's actions against Venezuela had everything to do with forcing them to trade oil in dollars.
Oil-rich countries are increasingly trading in other currencies - especially Chinese. That would lead to the end of the petro-dollar and the dollar's status as a global reserve currency.
What did Cuba do wrong? Americans are garbage to allow their government to blockade an innocent country. to remove the existing government with a more US-friendly (or bribed) government that will allow US companies to secure favourable contracts.
As for California homelessness, this is happening in cities and the most developed places around the world. It appears worse in America, but America has very limited civil services. They also have more egotistical billionaires who do not care about society as a whole, and probably buy up property to mess around with the natural supply/demand.
America's focus is to win the Tech and AI race. To hell with the rest of their society.
More than 70% of Big Tech workers in America were not born in America. It is not an American First agenda - it is Corporations first.
If you asked anyone in the world if they would prefer to live in California or the redneck states like Alabama and Kansas City, it is a no-brainer what the response would be.
The redneck states are carried by the Blue States. If the US were all red states, it would probably not even be a first-world country.
Texas is just a tax fraud that attracts companies and rich people with low tax rates (Like Ireland in Europe). Florida is a retirement home for rich people to dodge taxes.
