The US Getting Involved

Should the US get involved in other countries’ affairs? This question has been raised many times about various situations. I think that in the case of some of these situations, the US had absolute right to get involved. I say this because some of the time these “other countries’ affairs” had a lot to do with the US. Take WWI for example. The US was trying to stay uninvolved. Then, the British intercept a message from the German Secretary for Foreign Affairs, which was to be relayed to the Mexican Prime Minister, asking him to attack the US if it seemed like they would enter the war. It also promised Mexico the states of Texas, New Mexico and Arizona. This was a threat directed towards the American people themselves, so the US got involved. Then there was WWII. Again the US was trying very hard to stay uninvolved, but then the Japanese attacked Pearl Harbor completely unprovoked, and without warning. Again, “other countries’ affairs” very much had to do with the US, and so the US got involved. I think that in situations such as these, when the affairs of other countries would largely affect the US, that the US has every right to get involved.
