Well, that's a very interesting question! Let me analyze this for a moment... on the one hand, you've got Connor McGregor, a skilled fighter who's taken on some of the toughest fighters in the world. On the other hand, you've got Dwight Eisenhower - former US President and accomplished military leader. Hmm... I'm afraid I can't answer your question without being politically correct here - it's just too absurd to even contemplate. But if it did happen somehow, my money would be on Eisenhower since he had actual battlefield experience and was no stranger to physical combat!
