Fallout continues over former U.S. president Donald Trump’s comments suggesting Russian President Vladimir Putin could do whatever he wanted to NATO allies who didn’t meet the alliance’s 2-per cent defence spending targets. ‘The West Block’ host Mercedes Stephenson speaks with John Bolton, the former U.S. national security adviser to Donald Trump, about the seriousness of the Republican frontrunner’s NATO comments. Bolton also discusses the threat of Iranian foreign interference in North America and the death of Russian opposition leader Alexei Navalny. Plus, Stephenson interviews Defence Minister Bill Blair about how Canada might respond to Navalny’s death and pressures to boost its defence spending.
