Plus: Division on the home front can prevent victory over the enemy.
Good point, and another lesson we have not learned, because we allow the MSM to subvert the constitution by supporting the enemy.
**************************
During the Cold War, our “friends” on “the other side of the aisle” constantly sided with and aided and abetted our communist enemies - first the Soviets, later the Cubans and Viet Cong and after that Allende in Chile and then Ortega’s Sandinistas in Nicaragua. Then came Reagan, who drove the Soviets into economic meltdown and final collapse. For the most part, Marxism withered away all over the world.
Now the sworn enemy of our nation is Islam, and our “friends” on “the other side of the aisle” constantly side with Islam at large.
Can we infer that our principal threat is not the enemy at the gates, but the enemy within? Can we infer that is does not matter who or what is the foreign threat, but that the leftist malcontent will ALWAYS make common cause with those who hate us?
