fissures must be closed if NATO is to survive the decade. NATO will have to consider as appropriate to its vital concerns the very parts of the world toward which the Nixon Doctrine had sought to reduce American commitments.
There is considerable doubt in 1980 that the United States can continue to base its policies in Asia and Africa on the lessons of Vietnam. The Nixon Doctrine had identified limits to American commitment on the assumption that others would pick up the burden of peacekeeping. The upheaval in the Islamic world, the apparent willingness of the Soviet Union to spread into the southern hemisphere, and the inhibited NATO responses to these challenges have shaken this assumption. The direction for the 1980s lies not in a unilateral revival of the Truman Doctrine, but in a reinvigorated and unified NATO in which both authority and responsibility are more widely shared than in the past.
