A small fragment of the big POLITICAL picture of America ...
It is not Democrats or Republicans, it is the so-called Deep State, or the long-term political planning of the US military and those factions in government whose job it is to keep this country safe secure and plan for the future.
That is, a country does not spend as much as the rest of the world combined on the military to throw it all away. Strategists in the military, and private sectors look at hot spots in the world and the Middle East has been one since the formation of this country. It is to everyone's benefit not to have another superpower block that is insane or oppressed its people to the extent that happens in the Middle East.
I believe the plan is to creep up on Iran, the center of Islamic Radicalism, over time, which is why after 9-11 you heard people talking about a low-level war that would last 100 years to reshape the Middle East. When Iran falls, Saudi Arabia will as well, or it will just be waited out.
The reasons we do this are many. We use our military equipment to work the bugs out of it and evolve it. We have a trained military the best in the world to deter other countries from testing us. Our technology mainly derives from military spending - which when appropriate is released to private industry.
SIDENOTE - One way or another the American taxpayer funds almost all of the development of industry, technology, and even agriculture and infrastructure ... and yet, when the people ask for or even demand a return on their investment, they get called socialists or communists and denigrated. The other source of resources is nature, and we are hell bent on destroying it, but it is only recently that for example Alaskan residents have gotten a share of the resources of Alaska when they are developed. What about the rest of the country.
This is basically a brainwashing way to impress the mentality of undeserving slaves on Americans so they can be exploited - but when you go back and consider the wealth that was created by tapping working Americans' taxes, taking the First Nation People's lands and resources, building the country to critical mass with African slave labor - mix it all together, back date it, and this country owes its people a massive payback, and the people who have taken advantage of this system to lock others out owe the country a huge penance.
Put them together and think it through and we should being this country anew with a clear understanding of what and why our national goals are.
