1) The 'US Equivalent' of this operation would not be a spec-ops team with rifles... Maybe a spec-ops team with laser designators, but the preferred 'American response' since 1991 has been heavy precision-guided munitions (Tomahawks, Paveways and JDAMs)...
Failing that, the 'new' response would be to send the Army through to kick down doors & flatten stuff, ala Iraq... I wonder how well Hamas would fare against an OIF-sized force (what's the biggest armor formation the IDF has sent in since 2000, anyhow???)...
2) The Israelis are trying to ensure that no one in the vehicle survives. 30mm cannot achieve this, so they use Hellfires. It only fails when they miss (which is rarely)...
In short, you can't force peace, except through war... Hamas needs to be destroyed... Israel seems to be the only candidate to do it...
My suggestion: If the UN wants to prove their worth, why don't they put one of their vaunted 'coalitions' together and go flush out Hamas? I mean, they're such great peacekeepers, why not try it in the most obvious spot? Roll on in, kick Hamas in the ass, and secure the peace...
That's right... The UN has never found a peace it could successfully keep... Although an international force might have a better chance at destroying Hamas while avoiding inflaming the rest of the population (if there is a 'rest of the population) since Israel would not be involved at all...
Then again, they may need to slug it out untill the Palis are tired of dying, and do their own radicals in...
We'll see, my bets are on the last scenario, though...
