Well...I dont disagree with you but a preoccupied HAMAS is not a bad thing.
The future use of the arms are an issue, but I admit small arms, some Israeli civilians might die because of them, but they're not particularly important.
Preoccupation with infighting between Hamas and Fatah. Certainly not a bad thing for Israel or the US. Were Fatah to prevail, the PA police should be doing this job though, it would be a positive. However in the context of the article it's appropriate to remember the palestinian people, how many are peaceful I don't know, but they're our governments concern, and this kind of turf battle is going to be deadly for them.
If, and that's a huge if, it actually appeared that after 11 years of inaction the government was going after Hamas with the intent of disarming them, I'd support this. My guess, they could call on Israel for help. I just don't think that's happening here. Hope I'm wrong.
