How does rhetoric and sour grapes put out fires and will Trump thank Canada for their assistance?

Trump has once again politicized the California wildfires. And once again it is probably sour grapes that motivate him. And it will likely be sour grapes that motivate him to hold or delay aid. Canada has already sent a lot of fire fighters and equipment to help put out the fires and we are preparing to send more. But I bet Trump will not give a thank you and it will be sour grapes that motivate him not to. Cheers and happy weekend!
