When our allies commit atrocities...?
Let's take the US for example.
We are allies with many nations, that is to say, we ally ourselves with the establishment of that nation.
But what do we do when two of our allies are in disagreement with another?
Who do we support?
And as far as neutrality goes, it can also pose problems.
The Germans felt an immense betrayal when former chancellor Gerhard Schroder joined the Russians and allied himself with Vladimir Putin.
What do we do?
Do we say "How dare you Schroder? How dare you join that tyrant?"
Or do we just mind our business?
Our Saudi friends hate the Yemeni.
We supply them with arms. But why?
Because of a contract we have with them.
Lastly, who do we side with when two of our allies hate each other?
We are allies with the Turks and the Kurds and yet the former want to destroy the latter so that they do not pose as a threat.
Who do we side with?
Having Turkey as an ally has much more benefits than allying with Kurds who barely has an established country.
