The inability of the internet generations to use 10 seconds of their search engine of choice is pretty pathetic.
 
From Wikipee, who's rarely unbiased, but in this case managed some basic facts (Infogalactic is better):
 
Under current law, all male U.S. citizens between 18–25 (inclusive) years of age are required to register within 30 days of their 18th birthday. In addition, certain categories of non-US citizen men between 18–25 living in the United States must register, particularly permanent residents, refugees, asylum seekers, and illegal immigrants.[2]
~~
The illegals better run. I need popcorn for the Demorrhoid reaction.

In February 2019, the male-only military draft registry was ruled to be unconstitutional by a federal district judge in National Coalition for Men v. Selective Service System.[52] Following the ruling, the Selective Service's Legislative Liaison Jacob Daniels told reporters: "Things continue here at Selective Service as they have in the past, which is men between the ages of 18 and 25 are required to register with Selective Service. And at this time, until we receive guidance from either the court or from Congress, women are not required to register for Selective Service."[53]
~~
That was your guidance from the court. At any point you attempt to implement, you'll be shut down.
~~~
The Selective Service System considers the term "male" in the federal law to refer to the sex observed at birth, so trans women are required to register, while trans men are not.[54]
~~
Yeah, I need popcorn for the GOP response now. And the Demorrhoid freakout that transfemales might actually have to be treated like males. Basically, neither side has any intellectual consistency on this.
~~
First draftees are inducted: According to current plans, Selective Service must deliver the first inductees to the military within 193 days from the onset of a crisis.[75]
~~
After the President asks, and a Congress determined to fight everything he does agrees (good luck with that). Though they might do it just to be able to blame him. Because The Demorrhoids excel at fucking their own people in the ass to make a point that didn't need made.
 
And then you have to train them to do something useful.  And make sure they're reliable and not going to sabotage anything, which even volunteer millennials have done to high profile (That little bitch Bradley Manning for example).
 
So, at least a year. 
 
There are zero foreseeable future conflicts in which that timeframe will ever be relevant, and it's much cheaper to offer bonuses than fight the lawsuits or convene the boards, especially when a bunch of recruits never actually make use of the benefits in the first place.

So I'm going to disagree with a friend on a board that Selective Service is "Alive and well."  It's a barely breathing, corpulent relic that serves no purpose and exists due to the bureaucracy's inability and unwillingness to ever euthanize a terminally ill patient.

And speaking as a retired vet--we don't want the pathetic kind of untermenschen who need to be ordered to backfill support roles we can fill with reservists, retirees, civil service, and contractors for cheaper per-slot costs.  And we sure as shit don't want you pretending to be line troops. If you could pass the physical training. Which most of you soibois cannot. So bleat on Twitter, drink your energy drinks, eat your junk food or "organic" bullshit, watch your Youtube, and play CoD.  And otherwise keep quiet. The men will handle this.

And let's look at the history of these protests:

Rescue run to Grenada: "ZOMG! DRAFT!"
Dig out a guy in Panama: "ZOMG! DRAFT!"
Several debacles in the Balkans, Africa and Caribbean under Bill Clinton: INFORMATIVE SILENCE.
Expedition to Kuwait: "ZOMG! DRAFT!"
Operations in Iraq: "ZOMG! DRAFT!"
Operations in Syria under 0bama: DEAFENING FUCKING SILENCE.
Angry tweet about NK. "ZOMG! DRAFT!"
Single fucking missile on a legit target. "ZOMG! DRAFT!"

It's a childish protest bleat.

EDIT: in response to that last:

In response to my snarking commentary on hemorrhoid pussies shrieking about a draft, 
some liberal shithead called
Rebecca Anne Smith said: I strongly doubt that pattern exists anywhere outside of Mr Williamson's memory and that of people equally effected by bias confirmation.
Me: I strongly doubt you have a clue what you're talking about.

Nixon ended Vietnam and the draft, but somehow gets blamed for the war started by Truman.

Carter reintroduced Selective Service. Now, which party was he?  Oh, right.

I moved to the US in 1978, and was SERVING IN THE US MILITARY from 1985-2010 and watched nearly every minor operation lead to Demorrhoid pussies shrieking about a draft.  Except from 1993-2000.  The Balkans never happened and we don't still have troops there (except it did and we do) and "Clinton ended that war and brought the troops home" except they're still there.  Mogadishu never happened.

From Bush down, officials say there'll be no draft--but makings are there WAR IN THE GULF

Charlie Wrangel re-introduced a draft in 2003, shrieked to the press that Congress was considering a draft and it was all Bush's fault. No one else supported it, and his grandstanding stunt died in committee.


"Sooner or later, the government will need a draft to fight a longer or larger-scale war, or to maintain a permanent occupation force in Afghanistan, Iraq,"
https://hasbrouck.org/draft/draftandwar.html (which also contains the liberal lie that the Mujahideen became al Qaida)

"Widespread fears of a new draft crash selective service system."

The earlier ones are not easily found online, but I remember plenty of people railing about them both in person (including a couple of my alleged "educators") and in the press.

So anyone thinking otherwise can take their OWN selection bias and fuck themselves with it.
