The great thing about being in America, tbe, is that we are free to speculate and air our opinions openly without fear of repression or censorship. So, with the possible exception of what is determined as "Hate Speech", you can pretty much voice your opinions on any topic.
This is one of the most fundamental of rights.
The down side, in my opinion, is that there are people who are feeding these conspiracy theories for nothing more than their proverbial "15 minutes".
Then there are people who regurgitate these views simply to prance around the playground with the "I know a secret" song sung so loud, to try to make themselves seem important.
Did we (US) give Iraq WMDs? Yes, at that time he was our ally. Did we (US) train Al Quaeda, In part, yes. Do we (US) help our friends and allies? Yes (Mr. Finnish from above would be speaking Duetsch if we didn't help in the 1940s). Who is the first in line to help Israel with the neighbors that wish to push her 'into the sea'? And, more importantly, who is the country that keeps Israel from wiping her neighbors off the face of the map?
Now, having said all that, I will tell that I am a bit of a 'Isolationist'. I would like to see ALL of America's troops, forces, resources and assets brought back to this country. Let Afghanistan and Pakistan nuke each other back to the stone age... let Israel clear a 1000 mile "No Man's Land" around her borders... Let every POS despot and dictator in South America run their people into the ground while they all stay fat, rich and happy. Our troops belong in our country to protect our borders, both South AND North.
Won't happen of course, but that's my opinion and I'm free to have it.
That's what makes our system the best, and the one that most of the rest of the people of the world aspire to... so, is our (US) government screwed up? Hell yes. Do they do things to which I vehemently disagree? Hell yes. Are corporations running America for fun and profit. Most definitely.
Would I have any other system available in the world today. Absolutely not.
