Back in November, the US State Department warned that ‘mass migration poses an existential threat to western civilisation and undermines the stability of key American allies’. In February, in his address to the Munich Security Conference, Secretary of State Marco Rubio expanded on that theme.

After the Berlin Wall fell, Rubio noted, many in the West thought that ‘the end of history’ had finally arrived. Utopia was nigh. Western nations opened their borders, forsook spending on defence in order to bolster the welfare state and ‘outsourced’ their national sovereignty. This was, Rubio warned, to ignore both human nature as well as the lessons of ‘over 5,000 years of recorded human history. And it has cost us dearly’. He continued:

[W]e opened our doors to an unprecedented wave of mass migration that threatens the cohesion of our societies, the continuity of our culture, and the future of our people. We made these mistakes together, and now, together, we owe it to our people to face those facts and to move forward, to rebuild.

Britain and Europe’s leaders would be well-advised to heed the warning

That is the goal: a new western unity shaped by a frank acknowledgement of past folly.
