Answer: Nationalism was never such a pronounced element in the war; the most perfect and deadly weapon was used.
Explanation:
Nationalism resulting from uneven colonization among European countries is a key factor that led to the war. Never before has nationalism led to such a great conflict as was the First World War case. Nationalism is a product of the 19th century and all its perniciousness during the war. World War I took more casualties than any war before. The use of new technological advances for military purposes has been devastating. Thus, in the First World War, weapons appeared that had never been used in the war before. Tanks, planes, flamethrowers are just some of the new weapons used by the armies.
