Ukraine: Putin’s “red lines” and the “red lines” of the U.N. Charter and international law
Putin’s “red lines: have no meaning or significance under international law.
But Russia’s threats of an invasion of the Ukraine if it and NATO do not accede to Russia’s demands–for some kind of tong-term and binding security arrangements to prevent Ukraine from joining NATO or the EU–themselves violate the most fundamental norms of the United Nations Charter and international law.
These might be called, in a non-technical sense, the real “red lines” in international relations–the real “red lines” of the United Nations Charter and international law.
