You apparently do not understand the meaning of intent.
I recognize that there will be civilian casualties in war. That's a different thing than aiming at civilians. You aim at military targets and realize there sometimes will be civilians nearby. With an enemy like Hamas there might even be civilians being held at ground zero. That's not the same as aiming at them.
Huge chunks of cash and effective weapons are not "pouring into Palestine" from anywhere but the U.S. and only the Israelis are using them. Untermensche is right...the U.S. is an accomplice to these crimes. The same money would be better spent on humanitarian aid to the Palestinians, but we cannot get our government to stop. It is out of control... Have you any idea how we can make THAT STOP? Oh, no! the "war must continue till the last dog (Palestinian) is dead."
Denying the money and arms that are coming in doesn't make them go away. How do you think Hamas pays for the war???
As for humanitarian aid to the Palestinians, there's no way to do it.
If you provide cash they'll just use it for war.
If you provide things that would help the people but can't be used for war they'll just say no. (For example, the desalinization plant they have been offered.)
If you provide portable things Hamas will seize them and sell them to get money for war. That's why their hospitals have no medicine despite donations.
