Why was Great Britain determined to exercise imperialism in the Middle East?

The reason why Great Britain wanted to exercise imperialism in the Middle East was mostly because they wanted to show theworld that they were an important superpower and that they will not have their interests in oil thwarted by smaller conflicts in the Middle East.

The main reason why Great Britain was determined to exercise imperialism in the Middle East was to actually keep control over the Suez Canal. This canal provided the shortest route of transport between Great Britain and its colonies in Asia. Without this route, Britain would have had difficulties controlling the Asian colonies.
