Wars Started by President

Seems like most of those were more of conflicts than wars imo.(our involvement at least) I mean, did Obama really "start" or get us really involved in Libya Civil War? Did we even have boots on the ground? Most of those also seemed to be Indian wars which were just pitiful.(for the Indians)

Broadly defines "war." Forgot to add that

There's a bit of subjectivity in attempting to define anything from history, especially in classing events.

"Start" here is to be taken as "President whom initiated or escalated American involvement." Obviously Woodrow Wilson didn't start World War I (that one metal band did :P), but he did as far as America is concerned.

This may be somewhat off topic, but was the Contra Revolt under Reagan what the game Contra is made after?
