No surprises there then
The US has been fighting a series of interconnected wars for nearly 20 years now, with seemingly no thought of setting an end goal. I can only assume that the wars are for the benefit of whoever it is that makes the profits from those wars.
The travel policies detailed in the article seem to me to be an over reaction, but not a huge surprise. They are fighting a fair percent of the world at the moment, so are worried about the war being brought to US soil. Travel restrictions are a common feature of a nation at war, so I guess the big corporations mentioned here will just need to accept that there are sacrifices to make when you're at war.
The general public in the US seem (from the outside anyway) to be overwhelmingly supportive of their armed forces and oblivious to the damage all this killing is doing to their international reputation.
