All your allies have driven you to your border; those at peace with you have deceived you; they have prevailed against you; those who eat your bread have set a trap beneath you— you have no understanding.
Obadiah 1:7

All nations are ultimately tools of God's will. It's impossible to ally yourself against him because he owns all of your potential allies. He will reward your faithlessness toward him with faithlessness toward you from those you rely on most.
