Why did not sign the Tripartite pact?

A country may choose not to sign the Tripartite Pact for various reasons, including a desire to remain neutral in the ongoing conflicts of World War II, a commitment to alliances with nations opposed to the Axis powers, or internal political dynamics that favored non-alignment. Additionally, some nations were concerned about the aggressive expansion and ideologies of the Axis powers, leading them to seek alternative diplomatic paths. Ultimately, the decision would reflect a complex interplay of national interests, security considerations, and global geopolitical strategies.
