If you think a President of a Constitutional Republic has the authority to do that WITHOUT declaration, YES, you are a statist moron.only use words you know and don't make false assumptions, like you just did.
Why would the President of the United States need a 'declaration' to put down an insurrection.
Rebels attacked troops of the United States when they fired upon Fort Sumter.
Congress authorized the calling up of Militia and Abraham Lincoln authorized the blockading of rebellious states- after the rebels fired upon American soldiers.
