I think the simple answer is that the state of relative demilitarization the US has kept its subjects in is good for cultivating power when the first world has definite peace (and how could it not be, with all the US military bases in those countries?), but now that that peace is crumbling, NATO is forced to militarize more of its countries to deter/attack its enemies. That is, at least, an interpretation consistent with the headline and what Yog is saying, I think.
