The Globe and Mail reports in its Friday edition that President Donald Trump is amplifying risks for Canadian business interests in Cuba as he muses about a military invasion. The Globe's Rita Trichur writes that Cuba is already in the throes of an economic crisis that is being aggravated by Mr. Trump's ban on Venezuelan oil shipments. Ottawa cannot ignore Mr. Trump's threat of taking Cuba by force. Canada is Cuba's second-largest source of foreign direct investment after the European Union. Further instability threatens to permanently impair Canadian investments there, which include mining, tourism and energy. A top general has since said the U.S. military is not actively preparing for a Cuban invasion. But that nuance hardly dispels direct warnings from Mr. Trump, the commander-in-chief, that Cuba would be his next target after Iran. WestJet, Air Transat and Air Canada have temporarily suspended flights to Cuba. Sherritt International told investors last month that it had reduced operations at its joint venture in Moa, Cuba. The current economic crisis poses a serious challenge to both Canadian investment and bilateral trade. Canadian companies face collateral damage because of Mr. Trump's shameless lust for war.
