The Budapest Memorandum on Security Assurances, signed by Belarus, Khazakstan, Ukraine, Russia, the US, and the UK, obliging respect for signatories' borders and sovereignty, territorial integrity, economic security… is also what put Ukraine into the Treaty on the Non-Proliferation of Nuclear Weapons.

This will send the wrong signal to Putin, and prove his model of acquiring buffer areas around Russia actually works - next on the list are the Baltics, and Moldova perhaps.
I'm going to be in the trenches as soon as they get ideas about Finland - and you do not want that.
We have no business relying on the US anymore. They are too far gone. Their political rhethorics are polluted by Russian propaganda. (Just look at the rest of the comments here...)
It's time to get busy defending ourselves. Time for a war effort that doesn't involve merely wearing flag pins or doing cute street protests.
We need to be funding our own defence. We need to be sending actual troops in Ukraine, not just weapons. No more of this sidelines bullshit.
