Boycott US

Step 1: announce you will cripple the equipment you sell to allies, explicitly because you might attack them someday

Step 2: execute boneheaded policies to ruin both global trade but especially your own economy’s functioning, demonstrating a commitment to idiocy, angering the entire world in the process

Step 3: please buy our weapons

He can keep his crap
