Explanation:  All offered options except the first one, contributed in the long run to the First World War. The intertwining interests of the colonial powers on the one hand, and the rise of nationalism among the entities in the various empires on the other, have for decades created a tension that will result in a major showdown in WWI.

After that, Austria Hungary declared war on Serbia, after which great powers entered the war, to the extent of World War.

isolationism is a doctrine practiced by the united states for much of its history with the aim of not intervening in external affairs that did not pose a real threat to their country. the united states managed to maintain a state of political isolation throughout the nineteenth century and the first part of the xx. few nations have been able to maintain such a position for such a long period of time. historians argue that it is largely due to geographical reasons, given the physical distance between europe and the usa. uu the venataja of this situation is that the national state can spend its resources in satisfying all the needs of its inhabitants, without the need to invest in armament and equipment for a war that does not directly affect the country.
