Ho boy, here we go!
Before I address the immediate situation, please allow me to clarify a few things for the fine folks here:
1) Does Israel have a right to exist?
Yes, absolutely. Granted, their current borders -are- markedly different from the map drawn up by the UN partition plan in 1947, but that's a separate topic in and of itself!
2) Does Israel have the right to defend herself?
Yes, absolutely. All nations have the right to defend themselves when attacked. That does not however grant a carte blanche to use any and all force regardless of the 'collateral' damage it may cause. This, however, is a rule broken by just about everyone. The U.S broke it during WW2 when they flatenned Dresden (and again recently when they cleaned out Fallujah) The Russians broke this when they flatenned Grozny (and numerous other crimes against the Chechen people) The British broke this many times, but notably during the Boer wars when they basically put a large number of civillians in concentration camps to break spirit of the Boer fighters in the countryside. History is replete with countless examples all over the globe!
3) Is an attack against Israel automatically an attack against Jews and the Jewish religion?
No, not always. Quite often Israeli advocacy groups equate any and all attacks against the nation of Israel as motivated purely by anti-semitism by a group of people who are driven with the sole objective of wiping out the Jewish race. Any criticism of Israeli tactics is consequently seen as anti-semitic and siding with the enemy in their supposed goal of wiping out the jewish race. This is a key point. In order for unfettered military action to be justified, regardless of the casualties or long term rammifications it may have, the nation state of Israel and the Jewish faith must be seen (or be advertised) as one single unified entity that is under assault. Interestingly enough, some of the most ardent critics of Israeli policy such as Noam Chomsky, are themselves Jewish.
Okay, so now that we've gotten that out of the way, here's my position on Gaza;
Two wrongs don't make a right.
Is Hamas in the wrong for carrying out rocket attacks on Israel? Yes.
Is Israel justified in responding militarily to these attacks? Yes.
Are the current tactics and the nature of the strikes that Israel is carrying out the proper response? No.
What we see occuring today is proof that the IDF (or perhaps their political masters) did not learn from the Lebanese conflict in 2006.
What we are seeing is the same attempt at using shock and awe through a grossly disproportionate display of military power to unseat a political regime that Israel has deemed undesirable. This is nothing new.
This very same tactic was used on Serbia by NATO, and it worked in NATO's favor. It was used by the U.S with their aptly titled "shock and awe" bombardment at the beginning of gulf war 2 (or three or four or five depending on how you want to look at it) and it succeeded in nullifying resistance against the invasion. However the shock wore off, as it always does.
The IDF knows that the current bombardment will not remove Hamas or seriously hurt them. Organizations like Hamas are used to being targeted and are generally very good at dispersal and diffusion. This means that if Israel really does intend to remove Hamas through military firepower, mostly from air and artillery, realistically they would have to level most of Gaza or launch another prolonged ground occupation of the entire area. The real point of this bombardment is to punish the people of Gaza for allowing themselves to be led by a government that Israel finds undesirable. The proof of this will be found in the results; that Hamas will continue to exist and function despite the campaign. If this happens, it means one of two things
1) Israel knew that their campaign wouldn't seriously remove Hamas from the start, therefore indicating that they had an objective that was different from the one they publicly stated.
2) Israel failed in their objective.
Again, we hear the same line that Hamas is using human shields and hiding itself in the midst of a civillian populace.... well, seeing as Hamas IS the current government in Gaza, of course they're going to have buildings in the middle of civillian areas, just as the Israeli government has buildings in cities too.
I am not speaking in regards to the legitimacy of the Hamas government, although they were democratically elected, partially due to the fact that the populace was sick of years of corruption from their Fatah rulers and voted on an 'anything but Fatah' basis. Regardless, Hamas are the civil authorities in Gaza at the moment and should be seen as such, instead of merely being branded 'terrorists' or 'bandits'.
Furthermore, the nature of the terrain, in this case a very densely populated urban area, means that no matter how precise the IDF wants to be they will cause civillian casualties by launching airstrikes. Taking the path that they have chosen means civillian deaths are literally unavoidable.
As with all airstrikes on a densely populated urban environment, the majority of the casualties (casualties includes those wounded too, not just those killed) will be civillians and their wounds or fatalities will be from flying glass.
Every military organization on the planet knows this fact; that there is no such thing as a truly surgical strike in a densely packed city, as bombs create shockwaves that shatter windows and turn into flying shrapnel that injure or kill many people in buildings that can be up to several blocks away from the original target. And of course the flying shrapnel created from the initial blast which can be thrown great distances as well.
This is no great revelation, just basic physics which the IDF is well aware of.
So, this brings me back to my original point- two wrongs don't make a right.
Hamas is indeed in the wrong for their attacks on Israel.
Israel is in the wrong for carrying out their military response in a grossly disproportionate manner that will only create more martyrs and could ultimately strengthen Hamas, just as their campaign against Lebanon backfired and strengthened Hezbollah.
The current shock and awe being used against Gaza runs the risk of escalating things and widening the conflict in both it's scope and intensity. Already in arab countries across the globe there has been much talk of launching another intifada and Egypt is a big question mark- Hosni Mubarak is getting old and won't be capable of staying in power for very much longer simply by virute of his age. A moderate leader could take power, OR there is always the possibility that leadership more sympathetic to Hamas could be the result.
Only time will tell, but Israel has the power, ability and responsibility to expand their toolbox beyond large scale military action that ultimately strengthens their enemies.
