Islam is a religion of submission, not peace

USC:

The root word of Islam is "al-silm" which means "submission" or "surrender." It is understood to mean "submission to Allah." In spite of whatever noble intention has caused many a Muslim to claim that Islam is derived primarily from peace, this is not true. Allah says in the Qur'an (translated):

[2:136] Say (O Muslims): We believe in Allah and that which is revealed to us and that which was revealed to Abraham, and Ishmael, and Isaac, and Jacob, and the tribes, and that which Moses and Jesus received, and that which the prophets received from their Lord. We make no distinction between any of them, and to Him we have surrendered. [Arabic "Muslimoon"]

A secondary root of Islam may be "Al-Salaam" (peace), however the text of the Qur'an makes it clear that Allah has clearly intended the focus of this way of life to be submission to Him. This entails submission to Him at all times, in times of peace, war, ease, or difficulty.
