It's disturbing how difficult it is for the majority of American politicians to answer this question:
Who do you care more about the American people or Israel?
These politicians are elected to serve the American people ONLY, but you have this foreign interest group with deep pockets influencing how our politicians behave. It's as if the meaning of our greatest ally is this:
Our greatest alley = The foreign country with the deepest pockets and most control over the American political theater.
