Other than the reality that the humans of today have weapons that can destroy the world. Nothing much as changed since a humanoid applied a sharpened object onto a stick.
As a nation-state, we, as with our ancestors, have enemies foreign and domestic. Respective of wishing otherwise figurative and physical walls along with a potent armed force remains a critical defense to our offense. Wars won, or loss did not and does not deter the continuance of warring.
Importantly, however, the United States, since 1945, the most powerful nation within the free world, demonstratively lacked the will to eliminate worldwide threats to democratic principles and governess. From the end of WWII to present, America has expended trillions of dollars, hundreds of thousands of lives, rivers of blood, and gore for little to no measurable gain. Fearful of addressing the apparent and more concerned about the next election, then opening their eyes, political leadership has chosen meaningless words over decisive action. Eisenhower won the presidency by declaring that he will end the war in Korea. NOT if elected, I will ensure victory. Because of such non-action, Korea is a nuclear-armed gangster nation, a rouge menace to world stability.
This nation’s (presumed as enlightened) leaders, when threatened by a foreign enemy, are inclined to seek common ground, find an alternative, and as with governments of the past, exampled by North Korea offer bribes.
We Americans have developed and embraced a naivete more suited for a movie script or a comic book of Superman, Batman, and Captain America, than the actuality of inter-nation contesting.
Americans cannot accept the historical evidence that peace is a sublime idyllic. Peace is a non-achievable ideal and therefore should never be considered an actual policy goal.
It is not if I am right that has stupendous ramifications. It is if those that think and vote other wise are wrong that enables socialism via non-recourse statutory legislation and executive orders that matters.
Abruptly speaking: Withstanding the numerous mistakes of our past, if the Democratic Party wins the next election, America, as we conservatives have known, is trashed. Socialist and socialism will dominate every and all aspects of the heretofore American way of life. China and Russia will have won.
