Qualitatively, Hezbollah is described as ruthless and arrogant, willing to use physical force to effect political change, and prioritizing hard power. The party's strategy combines extremist rhetoric, tactical caution, and long-term risk taking. Arguably, its core source of strength is its effective, sustained violence. A number of sources say that Hezbollah's fighting strength is the foundation on which its political power, public support, and legitimacy lie. As one Hezbollah fighter said in 2017, "Either you are strong or you are weak, and if you are weak you get eaten. Now, Hezbollah is strong."
