What I am endorsing is taking the time and paying attention enough to know who are the threat and and who are not the threat.
I agree.
I think the idea Iran would let people (call them what you will) into their country to train and likely be armed only to come back and fight the US may qualify as posing a 'threat.'
So McCain was right although he labeled incorrectly.
These forces would not be a threat to US citizens if the US wasn't occupying their country.
It
doesn't matter what I will call them ...it
does matter what a presidential candidate will call them.
McCain is wrong.
