Good heavens, well it could be worse- he could have cited the "general welfare" clause.
The Articles of Confederation gave congress the powers so many want to give them roday: "making rules for the government and regulation of the said land and naval forces, and directing their operations."
But the Founders changed that in the Constitution- they wanted a strong executive. And one who could always act militarily in defense- on his own power.
"FRIDAY AUGUST 17th. IN CONVENTION
...Mr. MADISON and Mr. GERRY moved to insert "declare," striking out "make" war; leaving to the Executive the power to repel sudden attacks.
Mr. SH[E]RMAN thought it stood very well. The Executive shd. be able to repel and not to commence war."
The vote was 7 to 1.
Providing rules for operations is not the same as directing them. Not in this language.
