UK PM: we were warned with what Russia did in Georgia in 2008, Ukraine in 2014

Russia's actions in Georgia in 2008 and Ukraine in 2014, as well as the poisoning of Sergei and Yulia Skripals in Salisbury were warnings to the West, British Prime Minister Boris Johnson said in an opinion piece published by The New York Times on Sunday.

In the article Johnson says the West has failed to learn the lessons of Russian aggression from past events. 

For too long, we have turned the other cheek. And I know from speaking to my counterparts on recent visits to Poland and Estonia just how acutely they feel the threat. No matter how long it takes, we must prevent any creeping normalization of what Russia does in Ukraine, British Prime Minister says in his opinion titled

UK’s PM also claims the lesson from Russia’s invasion of Georgia in 2008 and seizure of Crimea in 2014 is that accepting results of Russian aggression merely encourages further violations. 

We cannot allow the Kremlin to bite off chunks of an independent country and inflict immense human suffering and then creep back into the fold. We must act now to strengthen Euro-Atlantic security. This includes not only bolstering NATO’s eastern flank but also supporting non-NATO European countries that are potentially at risk of Russian aggression, such as Moldova, Georgia and the nations of the western Balkans. And those that participate or enable Russian aggression, such as Belarus, will be subject to maximum sanctions, Johnson highlights.
