Who can declare a national emergency and send troops to war?
It is the presidents primary job as head of the US military to do these things. The office was created so that we as a country can make a swift response to such emergencies. The president has a limited budget in order to fund such actions and executive orders. It is the responsibility of congress then to decide weather or not to continue to back the president lead and officially "Declare war" or to recall the troops. The president can not use the military forces on US soil against Americans. In New Orleans, the military was used to assist in aid and rescue efforts only and could not be used as a force to restore order even to the point of having to retreat when fired on by civilians and let the state militia and local police deal with those situations.
Only Congress, according to the Constitution, has the power to declare war. Under the War Powers Act the president can send troops into battle, but then he must inform Congress, within 90 days, of his action and get their approval.

According to the constitution, absolutely not. Only congress can declare war which is stated in Article 1, Section 8. Although many presidents do send troops to battle without congress declaring war or even without consulting congress. To answer your question, they aren't suppose to but they do anyways.
There were two instances of this happening - the first was at the University of Mississippi in September of 1962, and a group of US Marshalls and 3000 federal troops were sent in. The one you're probably thinking of - and the one which the troops actually came from the National Guard (who had been federalized) - was the University of Alabama, which George Wallace himself had barricaded in opposition to integration. That was in…
Can congress rescind order to send troops once they have been deployed As in the case of Afghanistan?
As Commander-in-Chief, the President of the United States is the supreme commander of all the United States military services. As such, generals and admirals serve at his call. He can order bombings of foreign location, send ships anywhere, and send in troops as he wises. He can not declare war and must ask Congress for money if he plans anything that will take much time to do.
