why is it necessary, exactly? and who isn't putting in their fair share, in your estimation? and what threats might be so great as to justify high expenditure anyway?
I wasn't sure exactly but I know VDH is into this sort of thing so I searched "Victor Davis Hanson Nato Contribution" and snagged this result
"And when Berlin decides it will not pony up the promised 2 percent of GDP for its NATO contribution, other laggard countries follow its example. Only six of the 29 NATO members (other than the U.S.) so far have met their promised assessments."
