We are a globalised world, we need to think globally and not put up barriers, bla bla bla, and suddenly the border makes a huge difference?

We are just lucky that we have three oceans and a smaller population. 

And of course Muslims are more of a threat than non-Muslims. How many acts of terrorism have been committed in the last 20 years by other immigrant groups? The Vietnamese? The Chinese? The Philippinos?
