There is good news, and bad news if this is terrorism.
The good news: If it is terrorism, we can stop it completely by changing our foreign policy. On the other hand, the bad news is that as long as we continue to meddle in other countries affairs, terrorists acts will continue forever.
George Washington gave good advice.
The jihad on America has nothing whatever to do with our foreign policy, but everything to do with moslems' desire to convert/submit us to islam.
Are you delusional? Have you ever known any Middle Easterners up close and personal? These folks are fighting battles that stem from the Crusades! USA wasn't even around during the Crusades, battles that occurred before North and South America were even discovered.
I remember long conversations with a Lebanese friend in the 80s who blamed the wars in Beirut, and the taking and torture of Western hostages, on some policy promoted by Bobby Kennedy in the 60s. Bobby Kennedy was shot and killed by a Middle Easterner in the late 60s, still in jail for the crime, if you remember. I know Middle Easterners and their American symmpathizers today who bitterly blame the USA for the establishment of Israel in the 1940s and claim that that is what is causing the trouble today.
We could turn foreign policy 180 degrees and stand it on its head, and our enemies in the Middle East would trump up some other reason to target America and Americans. Educated Middle Easterners are astute students of history. They savor it and twist it in the retelling. Americans who slept through what little history they were forced to take in school are no match in a debate with an impassioned Middle Easterner, or one who has fallen uder their spell.
