A couple of examples to illustrate your comment.

1. Relationship between USA and Kurds. Kurds have been helping Americans, putting lives on the line, are a rare democratic and free side in the region, but are constantly being violated by Americans despite that.

2. Syria. No problem supporting the literal Alqaeda leader!

3. Just a history of supporting dictators. Chile and Americas, Asia, Europe (Spain, Greece, Portugal).

4. Even currently, no problem supporting e.g. Saudis.
