That's why they want DREAMERS to become soldiers, they won't have such loyalty.
As if Dreamers will ever make up a large enough percentage in the general ranks to pose that sort of threat. Never happen. Don't forget that even Dreamers have friends and family amongst the citizenry.
What of their fellow soldiers who wouldn't obey such urders? You think the traitors would be safe from them? And what of the chain of command that would forward such treasonous orders to the general ranks? Do you really think they'd survive the ensuing mutiny? They would not, and they know it.
This sort of talk is a slap in the face to our military folks, who (by and large) are better people than the keyboard jockeys who sit here slandering those who put their lives on the line to preserve their freedom.
