forget this immigration issue, the real danger now, as a result of this poorly thought out policy is blow-back and instability.
1a - Our troops are currently fighting right next to Iraqi troops. We rely on them for information and they fight in the same ranks as our Americans. Trump put American troops in danger and potentially harmed our alliances with Iraqi troops. This is a gross oversight that trump obviously never gave a single thought about.
This and the fact that judges and lawyers have denied the enforcement of this order, the chaos its created, the unpreparedness of the angencies to enforce it, makes it obvious trump aint playing 4D chess like you think he is. His move was grossly incompetent, and showed no considerations for the consequeses of his actions.
