I don't think it would ever come to that . If the situation occurred we would have done everything in our power to help the Mexican gov't,not support the terrorists. The middle east does not want Isreal to exist,period,thus they harbor and support terrorists.
I do think that over the years,Isreal has made mistakes,but they have finally followed through on their end,and it still didn't matter. They were not the aggressor this time.
Whatever the case,the world is a scary place right now. When I was in school,in history,when we studied the big wars,the way they would present it was ,"steps to the Revolution,steps to WWI,etc". You would learn about what was happening that finally escalated into war. Whats going in the world now, reminds me of that,radical groups terrorising people,crazy dictators,Europe basically apathetic,not wanting to accept reality,and just appeasing these nuts,hoping they will go away. I am very scared for us right now.
