Today aside (and I DO mean that):
Palestine isn't worth the sand they're fighting over. They SHOULD be taken care of, but I sure wish that Israel could have done it before this catastrophe happened.
Which puts the point on it: the Middle East is just a mess of infighting fanatical countries that can't even fight their own battles. They're not unlike a group of preschoolers in a sand box fighting over whatever the other has at any given time (yes, the temple, etc.) and then crying for mommy when they don't get their way. It's a common fear (and utterly within reason), that WW3 will start from within this cesspool.
And all this pain in the name of a non-existant god...what a bunch of fools.
Now, as for today:
ANY country that supports terrorism and ALL terrorist groups MUST be punished severely. If a person is even *capable* of an act such as today's, then that person should be put down for the sake of the common gene pool.
