It's not a very attractive option, because to do so will be a very bloody business, but unless Israel wants continuous rocket fire on the heads of its citizenry, it should finish Hamas in the Gaza strip.
Hamas is genocidal. We all know that. Their charter calls quite specifically for the murder of Jews... not even merely Israelis, but Jews as a group. Furthermore, Hamas has consistently shown that it is willing to act on that project, the Jew Killing Project.
Thus Israel has every right to finish them.
Will it do so? Heck, no. Israel will likely have some strictly limited objectives in the Gaza strip that may momentarily quell Arab-Muslim anti-Jewish violence, but there is no way that the west, following Obama's lead, will allow Jewish people to protect themselves.
Barack Obama doesn't actually seem to mind violence against Jews, because if he did he would never have supported the Muslim Brotherhood to begin with. Furthermore, as I never tire of pointing out, Hamas is the Little Brotherhood in Gaza. Hamas calls for the slaughter of the Jewish people and does whatever it can do to make that a reality. Meanwhile, the Muslim Brotherhood is the parent organization of Hamas and supports the goals of that organization.
And, lest we get distracted by shiny objects elsewhere, we must acknowledge that (for whatever reason) Barack Obama supports the Muslim Brotherhood. This is not "hyperbole." This is not rhetorical exaggeration. It is, in fact, a very simple observation of an easily verifiable truth.
Obama supports the Brotherhood. The Brotherhood supports Hamas. And Hamas is genocidal toward Jews.
Two plus two does, in fact, equal four, however much we might prefer it otherwise.
These are very simple, obvious facts that, if we care about our own well-being or the well-being of the Jewish people, we must acknowledge. It does us no good to pretend that reality is not real. It does us no good to pretend that the Brotherhood is "moderate" or that Obama does not really support them.
They aren't and he does.
Barack Obama has proven, time and again, that he is no friend either to the state of Israel or to the Jewish people. One cannot support the Muslim Brotherhood, an organization that is genocidal toward Jews, and still claim friendship with the Jewish people. It simply does not work that way and concluding so is nothing other than a matter of basic common sense and basic human decency.
Progressive-left western Jews are sometimes so "sophisticated" that they can honestly convince themselves that the guy kicking them in the teeth is really a good friend. I have no such sophistication. When someone kicks me in the teeth I do not pretend that they are anything other than the enemy that they are.
So, yes, Israel should eliminate Hamas in the Gaza strip by any means necessary.
But, sadly, do not look for that to actually happen. Jewish self-defense is strictly verboten, not only throughout the western left, but among western governments, as well, despite whatever lip-service they may offer to the contrary.
We are obliged to take our kick to the teeth and like it.
I recommend against.
