Question

after the attacks on September 11, 2001, how did the U.S. foreign policy change?

Answer 1

Well security changed that's for sure specially with other countries coming t o America

Answer 2

9/11 didn't radically change foreign policy, basically everything is still the same! The things that did change are Counterterrorism policies, the U.S. military as a provider of humanitarian relief. The U.S. military’s involvement in humanitarian assistance certainly predates the 9/11 attacks, but the scale and intentionality of its involvement have since increased to the point that such assistance is now a standard “tool” in counterinsurgency operations. In the days following 9/11, the U.S. government made it clear that American NGOs receiving U.S. government funds were instruments of U.S. foreign policy. Finally, since 9/11, legislation has expanded both the statutory definition of a terrorist organization and the interpretation of what it means to provide ‘material support’ to such organizations. The damages caused by this expanded understanding are manifold. On an individual level, it has severely restricted the U.S. refugee resettlement program, whereby a woman who provided water to an insurgent holding a gun to her head or a father who paid ransom to free his kidnapped child from a nonstate actor is deemed ineligible for resettlement on the grounds of having provided material support to terrorists. So what changed after 9/11 was the way humanitarian and military operations are done and there are many more military changes but why would we share those secrets with anyone from other countries that would be a National Security Breech! Military operations information are privy to our soldiers and no one else! That's the way it should be to protect our men and women in uniform!

Answer 3

international travel law customs also changed. Higher security in airports increased. The border on both ends of the country also are doing more security checks to make sure that international travelers are not terrorists and such

Answer 4

The precise relationship between the attacks of Sept. 11 and the decision to invade Iraq is complex. Purported links between Al Qaeda and Saddam Hussein’s regime were among the (many) reasons used to justify the invasion; as it turned out, the links were either exaggerated or simply false. More broadly, the general atmosphere created by the attacks — one, at great oversimplification, of fear and anger — played directly into the hands of those in Washington who had long wanted oust Saddam Hussein from power.

The human and financial cost to Iraqis and Americans alike of our “adventure” in Iraq has been terrible. Our invasion has also been a strategic fiasco. It diverted resources from Afghanistan during a period when we might have gained a quick victory; nearly a decade later, we are still attempting to pacify Afghanistan, with no end to our involvement in sight. The Iraq invasion also increased the power of Iran in the Persian Gulf; Tehran can now look to a sympathetic fellow pellete government in Baghdad. Not least, our invasion of Iraq helped create a new generation of terrorists (in Iraq and elsewhere) highly hostile to the United States.
