THE HAGUE: President Donald Trump met with Ukrainian leader Volodymyr Zelensky on the sidelines of the NATO summit Wednesday and suggested that increased spending by the trans-Atlantic alliance could help prevent future Russian aggression against its neighbors. NATO members agreed to raise their spending targets by 2035 to 5 percent of gross domestic product annually on core defense requirements as well as defense-and security-related spending. That target had been 2 percent of GDP.
