What 20th century events may have added to terrorism?(think wars, etc.)

Creation of Israel, USA invading Vietnam, Korean Wars, Iraq invading Kuwait and Soviet invasion in Afghanistan.

Explanation:

These are the few notable major 20th century events that come to my mind first. With the creation of Israel in 14 May 1948 (a state still not recognized by the majority of the Muslim world) caused international controversy and led to many Palestinian rebellions and ultimately the 6 days war. Not to mention USA invading Vietnam and the Soviet Union invading Afghanistan which caused one million deaths and contributed to the downfall of the Soviet Union.

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.

b or c im pretty sure
