I am happy to admit I do not understand some things...

 .. like this.

We are paying for munitions for Israel to further their war effort.

Now we are building a temporary port in Gaza to deliver food and medical aid to Gazans. These are the same people our money is helping Israel to buy arms to kill them.

All I can come up with is that this is a function of our government faced with two different positions. 

1. We want to help Israel after they suffered a horrible terrorist attack. and 

2. We also want to help those people who suffer in wars. In this case Palestinians in Gaza.
