James Mattis, retired Marine general and former commander of U.S. Central Command, testifying Thursday before the House Permanent Select Committee on Intelligence:
Whichever strategy is chosen, we should be reticent in telling our adversaries in advance any timeline that governs us or which of our capabilities we will not employ. Specifically if this threat to our nation is determined to be as significant as I believe it is, we may not wish to reassure our enemies in advance that they will not see American “boots on the ground”: If a brigade of our paratroopers or a battalion landing team of our Marines could strengthen our allies at a key juncture and create havoc/humiliation for our adversaries, then we should do what is necessary with our forces that exist for that very purpose.
The U.S. military is not war weary, our military draws strength from confronting our enemies when clear policy objectives are set and we are fully resourced for the fight . . .
Without firm action this poison will spread. The geography of the globalized world does not permit us to look away as if this is not our problem. Geo-political realities must be confronted and the enemy of our enemy may still remain our enemy, so the construction of an integrated Mid-East strategy to include confronting the Islamic State will not be simple. But that is now our duty to ourselves and to the world that our children will soon enough inherit.
You may remember him from the book Generation Kill
