The fugitive slave act was passed (a) as part of the compromise in 1850. The compromise was reached as an attempt to avert a crisis between North and South America. The issue of slavery had caused deep divisions between the North and South of America. The Fugitive Slave Act was a means of forcing the return of escaped slaves to their owners; even if the slaves had escaped to other states.
The Southern Plantations Owners (a) group supported The Fugitive Slave Act.
South Carolina (a) was the first state to secede.
We probably wouldn't have had as much technicologic inventions and the leader system would probably be messed up as well.
I presume your question is in reference to The Great War, which we now call World War I.
The days leading up to the Great War (World War I) were full of military buildup, military planning, and countries lining up with one another in alliance systems. The Triple Entente had Britain, France and Russia as allies. In between those countries were the members of the Triple Alliance: Germany, Austria-Hungary, and Italy, with Germany as the leading power in that group.
Because of the alliance system, Germany assumed that if a war began, it would need to fight on two fronts -- west and east. Germany assumed it would be fighting against both France (on its western border) and Russia (on its eastern border) if war broke out.
German Field Marshall Alfred von Schlieffen drew up war plans that said attack France first, quickly, and then hold that territory while deploying forces to contend with Russia in the east.
In 1914, when Russia mobilized troops to come to the aid of Serbia against Austria-Hungary in 1914 (after the assassination of Austria's archduke by Serbian radicals), Germany declared war on Russia. And when Germany went to war, the first thing it did was to march through Belgium to go and attack France. Up to that point France had not had involvement in the conflicts that had begun in the Balkans. Thus the war spread and quickly became a more global conflict.
The lack of ability to raise taxes to operate the national government, and the requirement for a unaimous vote of the state's to pass legislation. The federal government had no way to force the states to obtain the funds it needed to operate. State only sent funds it needed to operate.
