True, but Islam is derived from an Arabic rootword carrying a meaning of peace.
The question is how do Muslims define 'peace' and how do they keep it? Historically, by not submitting to Allah, there can be no peace.
No, because it involves a lot of commitment to be able to practice Islam faithfully.
2: 177 It is not righteousness that ye turn your faces toward East or West; but it is righteousness to believe in Allah and the Last Day and the Angels and the Book and the Messengers; to spend of your substance out of love for Him for your kin for orphans for the needy for the wayfarer for those who ask and for the ransom of slaves; to be steadfast in prayer and practice regular charity; to fulfill the contracts which ye have made; and to be firm and patient in pain (or suffering) and adversity and throughout all periods of panic. Such are the people of truth the Allah-fearing.
