Would Trump start a war over a handshake?

Yesterday when King Charles arrived for his state visit Trump greeted him with a handshake.
Then Trump tried his power move and pulled King Charles hand towards him but Charles pulled his hand back with ease. Trump tried it again and again and again but each time Charles pulled his hand back with ease. It looked like it really ticked Trump off - I don't think he will start a war over it - but you can bet he will have something nasty to say about Charles because of it. Cheers!
