Unification of Germany: Background and Analysis of the Two-Plus-Four Talks [April 16, 1990] [open pdf - 2MB]
From the Summary: "The decision of the Soviet Union to curtail sharply its presence and influence in Eastern Europe has led to a critical point in the process of resolving post-war Europe's central issue: the unification of Germany and the new Germany's role on the continent. The legal framework established in 1945 after Germany's unconditional surrender by the four allied powers -- the United States, the Soviet Union, France, and Great Britain -- has been altered by a series of agreements and by the Federal Republic of Germany's (FRG) steadily growing importance in political, economic, and security matters. The Two-plus-Four talks that include the two Germanys and the allied powers are intended to address the process of unification and the emergence of a fully sovereign German state. […] Great Britain has cautiously embraced unification and recognizes the Soviet need for reassurances as Moscow takes decisions to withdraw from Central Europe. London intends to pursue a settlement at the talks on Germany's future that will secure Bonn's continued commitment to NATO and to a politically visible nuclear umbrella for the Atlantic Alliance which includes a substantial U.S. political and military presence in Europe."
