Hammond once looked a picture of Charles de Galle and thought that he was looking at his reflection. So, rather than seek help for his narcissism and delusion, he started to act out his self aggrandising fantasy.
He is well known for Nimby decisions, so as any fall out will not be on Runnymede and Weybridge, his constituency, he doesn't care. It looks good, it looks military, it looks decisive, it looks like a decision the great man would take - Hammond, not de Galle!
