Israel invades the gaza strip.

The problem with the US getting involved is that it would only further violence, and in fact would likely escalate things. The Middle East is already a tumultuous environment. The only involvement the US should have is to broker peace between the two of them.

I'm 99% sure Hamas wouldn't even consider negotiating with the US.. Everything else has failed over the years, the only way to beat terrorism is by sterilizing it...
