S. government and politics are present throughout, embassies see lots of hardships. These same countries store biological/chemical weapons in caches in case of a war or other conflict. However, feeling threatened by the close proximity of these weapons of mass destruction, the U.S. has recently started frequent inspections in these caches. This is one more contribution to the hatred of the U.S. in the Middle East that is felt so passionately. This trend of outrage has been waging throughout the past two decades and cycles continuously in a circle of hatred and distrust.
The weapons used in places where U.S. embassies are located are also different. As mentioned above, these countries do have the power and knowledge to build such weapons as Anthrax and other biochemical artillery. People in such countries also are skilled in the "art" of small-scale bomb making. Products such as pipe bombs, anti-personnel grenades, and even rocket launchers are abundant and relatively inexpensive to produce. The popularity of this hatred is also greater than in the local situation. Political radicals such as Saddam Hussein can stir a crowd into such disgust with the U.S. that the average person would launch a military strike if given a second's chance. Riots on embassies usually form, sometimes causing more damage. To "better" the situation however, The United States government has begun to send in Special Forces such as SWAT team members and other counter-riot forces. However, as you can imagine, this only supplies an added hatred for the oppression of free speech that is being demonstrated.
Given the extremely unsuccessful ventures the U.S. has participated in, people have started hypothesizing new ways to deal with terrorism, both foreign and local. A small amount of people argue that we are being too lenient and that the government should increase their power and take the above counter-terrorist actions to a higher level.
