Lindsey Graham actually said...

We are trying to deter them from hurting us. We are not sending a bunch of people over there to invade their country without provocation.

All of this military force going that way is to deter them from being able to hit us and protect our allies.

Is it also fair to say that we do not have any intentions of invading North Korea at all?

It should be the policy of the United States to never allow North Korea to develop an ICBM with a warhead that could hit America.
