The present Turkish-American diplomatic crisis is fundamentally different from other such crises in 1964 or 1975. Turkish public sentiment in the 1960s and 1970s was largely pro-American (and anti-Soviet). Today, 79% of Turks have an unfavorable opinion of the US. Also, the earlier Turkish-American crises were largely single-case issues whereas the current one is multi-dimensional – and more difficult to resolve.
