What is the Unilateral Foreign Policy

Answer-Unilateralism is acting either without regard to the support or interests of other states. This is in contrast to multilateralism, acting cooperatively with other countries to advance common goals.

When a country uses unilateralism, it refuses to involve other nations in its foreign affairs. If a government wages war on a neighboring country without the advice of any outside groups, allies, or nearby countries, it's adopting a policy of unilateralism.
