Our borders need to be closed. Preferably with a mine field and an electric fence. This zone should be amply signed and warnings published about it. That way those who choose to die in the field or on the fence (as they are attacking our country) are taking their own lives into their hands.
Any active intervention on our part would be as an absolute last resort.
I have no problem whatsoever with people immigrating through the proper legal procedures.
Until next time.
Impossible!
