What is currently one of the methods for fighting New Terrorism?

Covert shadow wars represent a contemporary strategy in combating New Terrorism due to the need for flexibility and the element of surprise in modern conflicts. This method often involves discreet military operations, intelligence actions, and special forces engagements to disrupt terrorist cells without engaging in full-scale warfare or drawing public attention. Such operations aim to neutralize threats before they can materialize, focusing on quick, decisive actions that can include surveillance, targeted strikes, and supporting local forces. This approach recognizes the complex and decentralized nature of modern terrorist organizations, which often operate across different countries and use asymmetrical tactics.

The other methods listed do not align as closely with current counter-terrorism strategies focused on New Terrorism. For instance, invading sovereign nations may provoke further instability or resentment, global disarmament treaties might not address the immediate threats posed by terrorist groups, and increased tourism security, while important for protecting civilians, is not a direct method for defeating terrorism itself.
