"Remember that 9/11 occurred before the U.S. really bombed anywhere in the Middle East. To the best of my knowledge, Osama bin Laden's primary justification for 9/11 was the stationing of American troops on Saudi soil. "
Seriously? You go on to comparing the Saudi regime to germany of Korea?
Do you know how many people have been beheaded this year by the Saudis?
Ok, back to your point, Osama was trained by the CIA before the US started bombing anyone. So yes, his terrorist tactics were A OK so long as they were directed at the Soviet Union.
But as you say his main gripe was with US influence in the middle east. So lets look at that; Saudi Arabia, Egypt, Iraq and Israel get huge amounts of military aid. (I wouldn't be surprised if Syria got a huge amount of military aid from Russia, making these client states an extention of the cold war until the 80s at least)
What did these client states do with their weapons? Well Egypt was a beutal military dictatorship, it suppressed religious groups, and in doing so encouraged violent reprisals (ref: the muslim brotherhood) and is now slowly coming toward a more democratic state as the mulitary tries to avoid civil war. I'm guessing they are still arresting journalists.
Israel, Palestine, openair prison, illegal blockade, annexing land... Israel is the one liberal democracy in the region (with the possible ? of Turkey) and is a great place to live; feels very safe - for people from South Africa. If it were not for the Israel-Palestinian conflict i would have no issues with military aid to Israel in principle, except then the US went and gave them nuclear weapons (this is an open secret, because there isn't any point in giving them nuclear weapons to use as a deterent if you don't tell anyone)
Iraq was the great US ally after the Iranian revolution, with US support they invade Iran in the 80s causing one of the bloodiest conflicts in recent middle eastern history. Iraq had far superior weaponary but Iran had numbers, so those numbers died. And the war stalemated for nearly a decade. (After which Saddam decided he deserved Kuwait for being such a leal ally, and the US said no, enter US bombing in defence of a fairly just cause; stopping a dictator you created from taking over the region - then came sanctions which were working, but left most Iraqis in desperate poverty.)
Finally Saudi Arabia, the crown in your foreign policy achievements. The Saudis are a min contributor to OPEC and thus control global oil prices; their House of Saud and their Wahabi religious allies (read:fanatics) are guilty of oppression a home and terrorism abroad. Wahabism is something you can look up yourself, but it calls for violence against enemies of Islam. The Saudis are one of the few absolute monarchies left in the world, and can only exist through oppression and violence against their own people.
They support ISIS in an attempt to win Syria away from Iran and use American oil money (read:blood money) and guns to do it.
Even before the US decided to invade Iraq (despite having no terrorists there before the invasion) Saudi Arabia was brutal, and Osama Bin Laden was right to want to see an end to US influence in his country.
Imagine Brazil funded the republican candidate for President and lent him money in exchange for US oil reserves, positioned troops on US soil (just in case Mexico got uppity) and helped oppress US citizens. Now imagine not wanting to see an end to Brazilian influence in the US, go on, i dare you!
That said, i don't support how he went about it. But likewise, i don't support the SEAL team's murder of this man. Had he been caught and tried for his crimes, it would have been described as the show trial of the century, and become a rallying point for Extremist terror groups, so i understand WHY they did it the way they did. But i don't support going into any country and shooting people.
Just as you wouldn't support a call for Canadian Mounties to slip across the border and execute some US resident in the middle of the night, then extract him, and bury him in the great lakes.
There is a great reference somewhere in which a US president asks 'but why do the people hate us?' And it is explained to him; 'they are under the impression that we have harmed them by supporting oppression regimes, and they are right, furthermore we are right to support these regime because they guarentee our econmoic position in the world'
Lastly, all this military aid, essentially amount to large-scale corruption. Within the US lobbiest convince the government to spend money on military aid, the money never leaves the US it simply goes to amrs manufacturers who ship weapons to the middle east (among other places). The arms manufacturers pocket US tax payers dollar, a tidy profit; and the people of the middle east get to be shot, and bombed, and threatened with tanks.
The only ones to benefit are oppresive dictators and military contractors.
And yet the US cotizens do what? Complain that more needs to be done for security.
Well i ask you, whose security are you protecting??
