His mental decline won't lead us to war.
His willingness to do other people's bidding will lead us to war and his uncaring attitude towards America. His selfishness of getting more personal political and financial gain is what will get us there.
And it isn't just him that's leading us to war. His entire administration is part of it. They all cheer Ukraine, bow and clap when zelensky shows up on congress floor to ask for money, they all boo Russia and blame problems on them, they were part of blowing up nordstream, they agreed to place weapons near Russia's border and create a reverse cuban missle crisis, they appluad at handing Ukraine billions of dollars.
The entire Biden administration are to blame, not just sleepy Joe.
Helping people protect themselves against Russian aggression is the right thing to do. You Putin puppets are the ones doing Putin's bidding. You are anti-America traitors are the ones who are evil.
