Disagreement within alliances

Nature 
Disagreements within treaty organizations increase tensions within the alliance and provide exploitable opportunities for enemies of the alliance.
Incidence 
During recent negotiations between the USA and the former Soviet Union about reductions in nuclear arms members of NATO disagreed about which weapons should be reduced. There seems to be a lack of overall arms control plan on the part of NATO.
