Any president can start a war, and use the chaos of disorder that such a war creates as an indefinite argument for prolonging it. It's a war that keeps on giving. Failure means it's even more necessary to keep failing.
If you suspend the Geneva Conventions, give the green light to anything that will get intelligence, round up thousands all over the globe with reckless disregard for guilt or innocence, you are effectively and knowingly issuing orders to seize innocent people and torture them. Any president who decides to do that and then says it was not his intention to do that is a fraud or a fool.
