Où j'en suis dans mon devoir

I chose this cartoon by the cartoonist nate beeler. In this drawing, we can see President Obama is stating about how it should never be said that he failed to put border security into action. There is a wall with the words border security close by Obama. The crumbling wall contains a hole with a peeping immigrant. “12,000 Nat’l Guardsmen” is written on a Band-Aid that is covering a crack in the wall. But we can see in the reality in this cartoon frames Obama loosely enforcing border security on the Mexican border. The wall with holes and a band aid written with the words 12,000 national guardsmen suggest he is failing to secure the border all the while Obama is stating that he is securing the border successfully. I like this document because he exposes the reality of the facts and I think it is a efficient way To make people understand especially in this case because it is a touchy subject
