A coordinated mixture of A-10's (not a lot), a wing worth of OV-10A's (highly successful FAC & COIN a/c in Vietnam), and several air wings of Cobra gun ships and Blackhawk forward attack helicopters.
The situation has deteriorated to that. And these air wings should be associated with at least a division worth of Ranger level troops, and SF units capable of being rapidly moved into hot areas - and any smuggling operation should be considered "hot".
At this point, the only people doing this will be the States. The Federal government is being restrained by the traitors that are the Obama administration.
I agree. Protecting our borders it seems is not a high priority for this regime.
