Here's what most people miss — being an "ally" doesn't mean you agree on everything. It means you've decided that working together serves both your interests better than going it alone.
What "Ally" Actually Means in U.S. Foreign Policy

The Shifting Landscape: Allies That Come and Go
Geopolitics doesn't stand still, and neither do alliances. Some relationships deepen while others fray.
