After suffering from days on end of rocket and mortar attacks, the Isrealis exercise their right to attack those that attacked first. This is not a violation of international law, customs or norms, as some might suggest. Instead, it is implicit in international law, and authorized under the Geneva Conventions, that any state that allows its territory to be used to attack another state, cannot claim to be the innocent victim if the attacked state retaliates.
For those who would object to the use of force by Israel, I would ask if they could show me where they have called out against Hamas and their rocket attacks even once prior to Israel's actions. But popular culture, which is not the same as real culture, tends to view Hamas as the victim and Israel as the aggressor, and they will not be stopped in their one sided denunciation of who the actual victim is in this case. Those who object usually fall into one of two camps: Those of the moral equivalency crowd, and the Chomskyites. The first are neither moral, nor equivalent. All cultures are not equal. To say that we are no better than those who would stone to death a woman who was raped is to minimize the evil of the stonethrowers in order to ease their own conscience for doing nothing. The Chomskyites are predictably unthinking in that everything of Western values is evil, and everything not Western is good. It is a waste of time to even discuss anything with them.
I am not sure which group Youtube is associating with, but the Isreali Defense Forces are attempting to get out their side of the story through Youtube, since most of the supposed liberal media fail to report accurately or in an unbiased fashion, falling into one of the two camps listed above. Now Youtube is cutting off the IDF's access to Youtube as a form of censorship.
But as an example of what is going on in this situation, I invite you to watch this video of a strike on a Hamas Government building:
The secondary explosions would seem to indicate a large amount of substantial munitions or explosives were stored in the government building. But I am sure that they were intended only for peaceful purposes.
