Clearly Jenna you are a youngster. Israel has only a peace agreement with two arab states, the rest have never signed on, hence a state of "war" does exist. What happens now is a LIC Low intensity conflict. Take a look where fatah and hamas store their arms depots...thats right Jenna in the midst of civilians. Not a nice thing for these heroes of the Islamic movements to do right. Their constant launching of rockets, mortars, suicede bombers, will always force a response from ISrael. You should be very happy that indeed no state of wear exists between Israel and the palestinian authority, as it would be a short and sharp war with the majority of palestinains terrorists wiped out. Perhaps you should thank Allah for ISraels patience so far.
