While claiming that he just needs a “limited” war against Syria to back up his “red line” threat, President Barack Obama is actually seeking a far broader mandate from Congress. The authorization would allow Obama to take any action that he “determines to be necessary and appropriate in connection with the use of chemical weapons or other weapons of mass destruction in the conflict in Syria” as well as acting to “prevent or deter the use or proliferation” of the weapons or to “protect the United States and its allies and partners” from the weapons.”
Indeed, it reminds one of the authorization leading into Iraq with only the 9-11 angle replaced by a chemical weapons rationale. The Iraq Resolution or the Iraq War Resolution (formally the Authorization for Use of Military Force Against Iraq Resolution of 2002), stated “That the President is authorized to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons.”
Now replace the terrorist attacks with the chemical attacks and you have our latest blank check demanded by a President. The language accomplishes two things. It allows members to claim that they merely wanted to protect the nation while making it unnecessary for the President to ask them again (and expose them to difficult votes). This is how politicians like Hillary Clinton and John Kerry voted to allow the Iraq War. While they later claimed that they had no idea and were misled, they ignored critics at the time questioning the evidence and objecting to the blank check language of the authorization. They also took no action later as the war killed thousands of U.S. personnel and spent hundreds of billions.
Nevertheless, democrats like Nancy Pelosi are demanding action and once again absolute (and blind) loyalty to Obama. The speech for Obama in the final vote has already been written (with a few modest edits):
Once more unto the breach, dear friends, once more;
Or close the wall up with our  dead.
In peace there’s nothing so becomes a man
As modest stillness and humility:
But when the blast of war blows in our ears,
Then imitate the action of the tiger;
Stiffen the sinews, summon up the blood,
Disguise fair nature with hard-favour’d rage;
Then lend the eye a terrible aspect;
Let pry through the portage of the head
Like the brass cannon; let the brow o’erwhelm it
. . .
Dishonour not your mothers; now attest
That those whom you call’d fathers did beget you.
Be copy now to men of grosser blood,
And teach them how to war. . . .
For there is none of you so mean and base,
That hath not noble lustre in your eyes.
I see you stand like greyhounds in the slips,
Straining upon the start. The game’s afoot:
Follow your spirit, and upon this charge
Cry ‘God for [Barry], [America], and Saint George!’
