“It ain’t what it used to be cartoon” Who is that in the cartoon? What is the purpose of the cartoon?

Uncle sam. this cartoon is in reference to the Neutrality acts of the 1930's where the US didn't want to get involved in world politics due to the devastation of WWI, and it is largely believed that these worsened the situation globally. It has next to nothing to do with an immigration crisis that was essentially created by US-Russia relations over the past 50 years. In total, an estimated 6 million people and seems to be dwindling off. do you like my 80085?
