It's made me reconsider visiting. ATM, if I do go, I'll most likely go via Ireland where most of the border checks are done before getting on the plane rather than when getting to the states.

However, the article you linked to states its not an offical travel warning, more like an advisory.

> But they also stressed that this change does not count as an official travel warning

The Ireland tip is a great shout. My brother-in-law holds passports for the UK and another country that is not on the USA's christmas card list, he does all his US business flying via Ireland.
