Prime Minister Trudeau will meet U.S. President Donald Trump in Washington on Monday. There is both hope and concern as the young Trudeau (45) is confronted with President Trump (70) demanding renegotiation of NATFA but also aware of essential US markets in Canada. Trump is likely to press Trudeau to pay the full amount Canada is committed to contribute to NATO. It is a sore point among Americans that they carry the heaviest burden for NATO because its members renege.
