OTTAWA - Donald Trump is getting on Justin Trudeau's case - again.
As the prime minister prepares for the upcoming NATO summit in Brussels, the American president is scolding Canada for not meeting the alliance's defence spending targets.
In a June 19th letter, Trump says there is ``growing frustration'' in the U-S with NATO allies like Canada that haven't increased defence spending as promised.
Trump warns that the United States is increasingly unwilling to ignore NATO's failure to meet shared security challenges.
The letter comes at an already tense time in Canada-U-S relations, with Ottawa and Washington feuding over trade.
That relationship took an ugly turn following the recent G-7 summit in Quebec when Trump called the prime minister ``dishonest and weak.''
The Liberals promised last year to boost defence spending by 70 per cent over the next decade - but even that would still leave Canada short of NATO's target of spending two per cent of G-D-P on defence.
