There will be a world war.

We're not defending our country or fixing it.

We can't trust the politicians.

The ONLY logical outcome is invasion. Nobody else to save us, other countries will step in sooner or later.

Think of it like this:

If you got 2 people having a dispute, without someone stepping in it'll get to violence and maybe death.

When you can call the police, there is far less violence. Issues can be resolved civilly.

We now have 1 person causing issues and there are no cops to step in to help. We either need to fight, wait for death, or wait for a 3rd party to intervene.
