KYIV, Feb 19 - British Prime Minister Boris Johnson said he believes Russian leader Vladimir Putin might be thinking “illogically” about his initial plans to invade Ukraine, Reuters reported.

In an interview with the BBC on Sunday, Johnson said that threats of imposing sanctions onto Russia for the invasion “may not be enough to deter an irrational actor and we have to accept at the moment that Vladimir Putin is possibly thinking illogically about this and doesn't see the disaster ahead.”
