As much as conservative churchians may think America is doing the world a favor via its endless warmongering, there is simply no biblical justification whatsoever for any of America’s current wars.
America is not ancient Israel; the American military is not the Army of God; and NO American president is God.
Turn off Faux News and most of what passes for Christian media nowadays and pick up your Bible. Start with Deuteronomy 28 and you will quickly learn that God would not unconditionally always and forever bless Ancient Israel if they ignored His teachings. Why, then, do so many Americans think that God will perpetually heap unconditional blessings on America?
Ultimately, God would let Ancient Israel fall under several evil foreign tyrants. Why, then, does anyone think America will last forever?
