A sign of maturity is owning up to your weaknesses and mistakes. Something that our leader is sorely missing.
Another sign of maturity is being able to realize your own strategy doesn't work and being able to admit to that. Actually, scratch that, our leader has no strategy at all, he just wings it. I don't think he even has the capacity to know other countries are doing better.
The funny thing is, if he sorely wants to be re-elected, the smartest thing to do is to keep us all safe.
