But Brexit did not make it easier for Putin to invade Ukraine, did it? The response has been as unified as it would have been if we were still in, because the response is about Nato solidarity, not EU solidarity.
One thing that made it a lot easier for him to invade was Germany's very misplaced, foolish and naive energy policy, as a result of which the Russian war machine is still being funded every single day in spite of sanctions.
I'm not sure what that opening conjunction links to, but anyway...
(a) It is entirely possible to think Brexit is a steaming pile of shite and that Germany's energy policy is also fecking daft. I know this because I think that.
(b) The fact that BJ got elected on a Brexit platform and then proceeded to fill his Cabinet with incompetent pro-Brexit-yes-people who are now fucking up something as basic as a system to allow war refugees to enter the UK, leading to justified criticism from EU partners, doesn't help with a "unified" response on that level. (I realise you didn't refer to this aspect, since your focus is on NATO, not the EU, and to war, not those it has displaced, but the point stands.) The UK response is also a result of the xenophobia fed by Brexit propaganda. cf posters on MN saying the UK is already creaking at the seams, as though Moldova were wealthier and better able to host thousands of refugees...
(c) There is credible evidence that Putin encouraged Brexit, interfering in the referendum in order to destabilise the EU. The fact that he misdiagnosed the outcome of that plan as regards the response to his invasion, as he has misdiagnosed much else, doesn't detract from that fact.

To speak of linkages most certainly doesn’t mean that Brexit ‘caused’ the Russian invasion of Ukraine. I’m not sure that anyone is actually claiming this (reports of people doing so seem to distort what is actually said, though of course it’s always possible to find a tweet from someone or other saying almost anything), but if they are then it’s nonsense.
However, it can be said that Brexit is one aspect of the more general fracturing of the liberal international order in recent years - a topic well beyond the scope of this blog – which has made its response to previous Russian nationalist aggression so ineffective, thus encouraging Putin to this latest act of war. But Russia’s invasion of Georgia in 2008 and its annexation of Crimea in 2014, and the limited international reaction to these, both pre-date Brexit.
It can also certainly be said that those campaigning for Brexit contributed to enfeebling the international response to those earlier aggressions. Both Nigel Farage and Boris Johnson used the Crimea annexation as a stick to beat the EU with, claiming that it had unjustifiably provoked Russia by offering Ukraine an Association Agreement.
