To borrow one from you, Madanthonywayne:
It's always tough to respond to one of your posts because they're so damn long, I'm always putting it off.
It's always an interesting experience to attempt to respond to your posts, largely because I question the relevance.
For instance:
You just do the best you can to handle each problem as it comes. If we hadn't allied with the Soviets against the Nazis, we might have lost WW2.
Now, aside from the question of how Germany would hold Europe, or better yet how they would have succeeded in prosecuting a war against the United States (after all, they declared war against us), there is still the question of relevance. More specifically, we might look at a line of historical continuity:
Mistake 1: U.S. invades Russia, 1918-1920, initiating its opposition to the Communist Revolution
Mistake 2: In interest of Cold War against Soviet Union, U.S. topples democratically-elected Prime Minister of Iran and supports the Shah, 1953-1979.
Mistake 3: In interest of counteracting Iranian Revolution, U.S. begins normalization of relations with Iraq, supplying weapons to known human rights abuser and accused terrorist sponsor, 1982-1990.
Mistake 4: Having dispensed with our need for Saddam Hussein, United States begins long campaign against Iraq, leading to 2003 invasion, 1991-present.
We raised the Cold War (#1), opposed democracy (#2), supported a madman (#3), and invaded a sovereign nation on false pretense (#4). The best line of historical continuity strongly suggests, if we take your assertion, that we propped up dictators in order to cover for prior mistakes.
Funny you should mention prescription drugs. I think when a whole class of painkillers is pulled for threatening the lives of its users, we might consider whether or not commercial demands compelled the manufacturers to rush just a little.
And that's the politically-correct version. They knew. And they still went ahead.
Interesting comparison.
