This piece of disgusting Euro-trash whines like a big pampered baby over sending Prince Harry to war. Yes, it was very expensive. Yes, that time and money could have been spent on something that would (in your view) be more productive.
But he’s the prince. It’s in his blood. He is in a unique position of saying “There’s a war on, and you can’t keep me out of it!” He has influenced (shamed?) his older brother, the future King, to do the same. That’s why we have Princes and Kings, dammit!
If young Henry Wales wishes to leave England and set himself up a nice warrior kingdom, I can be packed in a matter of hours.
