Yes because you can deal with Soviets. They may be evil but they are sane. You can’t with Muslims.
The Neo-Soviets and Chicoms are dangerous, but sane.
The Iranians (and their Hezbollah/Hamas puppets) are not right in the head, but can still be talked with. They are still dangerous, but will not attack the US unless they are going to go to war with us or Israel. Same for North Korea.
Al Qaeda, on the other hand, is totally crazy and will attack anybody, even fellow terrorist groups and rival AQ cells!
