It matters not what we're going with.
This is one show where Trump is second banana to Putin.
And Putin is going with his long-standing orders to Trump to cut off or indefinitely suspend the delivery of U.S. military aid to Ukraine. I also suspect that these North Korean soldiers are a bluff to keep Ukraine busy on their Eastern border while Putin plots to start lobbing missiles into Poland and other NATO States as soon as Trump can browbeat and terrorize the U.S. Senate into removing the U.S. from the North Atlantic Treaty Organization (NATO) thus leaving U.S. allies in a "surrender or die" position as Russia runs roughshod over Eastern Europe.
In the meantime, Trump has once again diverted attention away from a more deadly serious war abroad that, right now, is in its final planning stage.
Maybe they're cackling because they're watching a very stupid President of the United States self-immolate.
