The United Nations Security Council took significant measures in an effort to combat terrorism by adopting Resolution 1390. This resolution aimed to establish an arms embargo against the Taliban and al-Qaeda, a response to the rising global concerns surrounding their activities following the events of September 11. The resolution called for member states to prevent the supply of arms and related materials to the Taliban and al-Qaeda, along with freezing the financial assets associated with Osama bin Laden and his organization. This multifaceted approach sought to diminish the resources available to these groups to carry out their operations.

The resolution represented a united front by the international community against terrorism and highlighted the need for cooperative measures to ensure global security. The UN Security Council emphasized the necessity of implementing and enforcing these sanctions rigorously and called upon nations worldwide to act decisively. This action underscored the importance of international collaboration in countering terrorism and addressing security threats that extended beyond national borders.

In addition to preventing arms supplies, Resolution 1390 paved the way for further actions aimed at dismantling the operational capabilities of terrorist organizations by promoting compliance with existing anti-terrorism measures. The resolution urged countries to share intelligence and to work together on investigations that could expose and disrupt terrorist financing and operations, marking a critical step in global counter-terrorism efforts.
