Just a thought..... Knowing that Israel is very good at counter terrorism and should know every move hamas is making..... could have or would they have let something like this happen so they have a reason to completely wipe them out of the region?
No. We are good at counter-terrorism when our country isn't divided and our politicians don't ignore the information because it doesn't conform to their political ideology. Does anyone think our border not being secured is so we can have an excuse to attack Mexico and South America? Terrorists take advantage of a divided country. It’s why they use propaganda in the first place to divide it.
Israel understands this could cause fighters from all over the middle east to flood there to fight. They now have an almost impossible task of threading a needle to defend themselves and not provoking that.
