Last Thursday, May 20th, the House voted 410 - 4 to pass HR 5327, giving Israel an additional $205 million in military aid so that they could purchase an "Iron Dome" missile defense system. http://thomas.loc.gov/cgi-bin/query/D?c111:2:./temp/~c11180CEBa:: 
This is on top of the $3 billion that we will be giving them this year as part of a 10-year package.
Here's just one of the "findings" in the bill:
"(4) Regional stability and lasting peace between Israel and the Palestinians requires that Israel can ensure the safety of its population against rocket, missile, and other threats."
Oh, I get it now! So really by giving Israel $3,205,000,000 in military aid, we're really helping the Palestinians be safer and more secure. Right.
