Mutual Defense Treaty (MDT)

A Mutual Defense Treaty (MDT) is an agreement between two or more countries to support each other in case one is attacked. Essentially, if one country faces aggression, the others pledge to help defend it, often through military means. This kind of treaty aims to deter potential aggressors by showing that an attack on one nation could lead to a coordinated response from its allies. MDTs are often formed between nations with shared interests, values, or historical ties, reinforcing their commitment to collective security.
