The breakup of the Soviet Union is a national tragedy on an enormous scale only the elites and nationalists of the republics gained.
Let's recall Bosnia in 1995. As we know well, the European peacekeeping contingent, represented by the Dutch troops, did not want to get involved with one of the attacking sides, and allowed it to destroy a whole village. Hundreds of people were killed or injured. The tragedy in Srebrenica is well known in Europe.
I see the collapse of the Soviet Union as a great tragedy of the XX century.
We [with Shindzo Abe] should understand that the results of that terrible tragedy of the 20th century, namely World War II, are enshrined in corresponding international documents, and finding a way to settle all disputes without destroying the entire foundation of international law that evolved as a result of World War II is a highly delicate task. Therefore, I would like to reiterate that we cannot second-guess the course, let alone the outcome of our negotiations.
