Only Congress has the right to declare war, but the president is the supreme commander of all of the U. S. armed forces, including state militias.
The president is the commander-in-chief over all military powers in the US. He consults with the military chiefs of staff but he is the commander and they serve at his will. Congress determines what the military will be and appropriates the funding for it.
If only Congress held military powers, then any action would be too slow; with the president holding military powers, a quick, immediate response could be made without political squabbling.
