Your insinuation that the UK will implement a Ukraine war draft in order to advance a totalitarian agenda is weird, unnecessarily conspiratorial, and dilutes your point.
I encourage you to make one point and to make it well.
It's reasonable for people who want to seriously address the very real and legitimate problems with this kind of "wiretap" legislation to not want extraneous issues derailing the discussion, as having their concerns conflated with more conspiratorial-sounding ones makes them far easier to dismiss.
As demonstrated by COVID regulations in emergency the law can be changed very quickly.
Modern armies (like NATO members) have really got very little to gain by conscription. Being a modern soldier has very little to do with being cannon fodder.
Unfortunately, in Ukraine both sides are cannon fodder again because modern anti air defenses are so good that the fighting relies on 155mm howitzers again. Which NATO has just run out of and has no capacity to manufacture in sufficient quantities.
That’s scary. If 31 countries cant get their act together to manufacture basic weapons then we are in no better shape than russia. Should they win the war in ukraine and decide to attack other countries we’d be caught with our pants down.
To be fair it appears that Russia is using 10x more shells then they manufacture in a year so once they run out of their old soviet stock pile things will go south for them.
Conscripts are only good for defense - they know the area and the local language/customs. Additionally, they stand to lose their friends, family and possessions, so they're motivated to do something about that.
None of these advantages apply on the offense.
