The Brexit Threat to British Security

Perhaps the recent attack on a former Russian agent in a quiet English country town will be enough to show Brexiteers that a “Britain alone” is a “Britain vulnerable.” But it is also possible that by the time UK nationalists discard their ideological blinders, it will be too late.

LONDON – Some moments in history are steeped in irony. To glimpse a current example, look no further than the United Kingdom. As the Brexit negotiations with the European Union approach a tipping point – this month’s European Council meeting – the British government is seeking its scorned European partners’ help in its dispute with Russia over the attempted murder of the former Russian double agent Sergei Skripal and his daughter in Salisbury, England.

But even before the brazen attack on the Skripals – targeted with the Soviet-designed nerve agent Novichok – Prime Minister Theresa May had become more forthright in highlighting the values and interests shared by the UK and the EU, including with regard to security and defense. Indeed, at last month’s Munich Security Conference, she proposed a “deep and special partnership” on such matters.

In May’s preferred scenario, the UK would continue to participate fully in EU agencies like EUROPOL, while upholding European Arrest Warrants (EAWs). Moreover, the UK would maintain its involvement in existing and future EU Common Security and Defense Policy (CSDP) missions, and coordinate with the EU on sanction regimes under the Common Foreign and Security Policy (CFSP).
