This would be a good time for Cruz to announce he would order production of the abandoned NEUTRON bomb.
It keeps invaders out of the corridor while leaving the countryside undisturbed.
Forget the neutron bomb. Too pacifistic IMHO.
My preference would be a modern version of the B-41 on top of a ballistic missile. That is 25 megatons of all American three stage thermonuclear firepower!
Those Moscow bomb shelters cannot be deep enough to avoid that kind of consequence.
