I wouldn't say it's Abrahamic religions that make the West more of an individualist civilisation. If anything the Abrahamic religions made it more collectivist especially at a time when the Church used to be very powerful before separation of Church and State become the norm. After all Christianity is an Eastern import. The individualism stems more from classical Greek philosophies and the Renaissance period than Judeo-Christian teachings.
The Western world was full of bickering city states and relatively speaking small countries compared to the large empires of the East. Notable exceptions of course include the Roman Empire and the Seleucid Empire. It was relatively recently in history (16th century onwards) when the West really took off and left the rest of the world behind in science and technology did it gain large Empires and those conquests were treated as more of a colony than an integral part of Empire if you will. The modern individual nation state is a very Western oriented idea too.
