The only reason that the U.S. has been able to interfere in the internal affairs of so many other countries over the years is that we have allowed the Federal government to consolidate and centralize its power and reach far beyond its Constitutional power to defend the country. Very little of what we have done in the past 100 years has been strictly for defensive reasons.
And, contrary to what the Left and their media sycophant media drones will tell you, it is the Progressive Left who has lead us into the most wars in the past 100 years. This is because of the power it gives them to consolidate their power even further.
"Of all the enemies to public liberty, war is, perhaps, the most to be dreaded, because it comprises and develops the germ of every other. War is the parent of armies; from these proceed debt and taxes and armies are the known instruments for bringing the many under the domination of the few. In war, too, the discretionary power of the Executive is extended; its influence in dealing out offices, honors, and emoluments is multiplied; and all the means of seducing the minds, are added to those of subduing the force, of the people...[There is also an] inequality of fortunes, and the opportunities of fraud, growing out of a state of war, and....degeneracy of manners and morals....No nation could preserve its freedom in the midst of continual warfare." ~ James MadisonWill we be lead blindly to war?
