Excellent question. Star for you. Don't expect too many intelligent answers from the bleeding hearts tho!
I can answer yes to all of them and my plan is the only one that will work: universal worker's rights, freedom of movement and equal benefits for all people. Borders should stop no one. You might think you can't afford decency, that the poverty of others makes fairness unlikely- it's still the only good solution, the only way to guarantee lasting safety.
Plus the US signed onto the idea in 1948 when they agreed to the UN charter. It's referred to as the universal bill of rights. Your Arizona law is illegal under international law because it goes against that treaty.
Giving the world the impression you don't care will definitely NOT make you safer.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
