Absolutely, and in the strongest possible terms I will not sign this, because the Palestinians are not "innocent civilians". They voted for Hamas. Hamas is a terrorist organisation that openly called for the destruction of Israel prior to the last Palestinian election, and a majority voted for them, presumably fully aware that Hamas intended to attack Israel.
If you believe in the democratic system, then you must also believe these rocket attacks are supported by the majority of Palestinians, so therefore the inevitable consequences must also be supported by the majority of Palestinians.
I hope there is a soloution to the middle east, but I fear that, much like the Germans who voted for Hitler prior to WW II, the Palestinians who voted for Hamas are responsible for much bloodshed on both sides, now and in the future.
