I do think the running of States is like a well-oiled machine, however, in that the equilibrium of power lies toward the federal government and I think this is the right thing to do because regions with too much power can cause wars and deaths as arguments arise. If the states are not bound by laws they cannot adjust then they would not be united. The principle of states' rights was the basis on which many of the political battles preceding the American Civil War were fought. Slave states asserted that they had the power to maintain social institutions, particularly slavery, in whichever way their state legislatures, the governing body in a state that deliberated on up-and-coming legislation, saw fit, while Midwestern and North-eastern Free States asserted that they had the power to exclude slavery and slaves from their territories.
The South's secession was the greatest assessment of States' Rights, and its supporters failed to reinforce their purpose. The United States would become a unified nation, and the state’s "right of secession" was almost entirely dissolved. When Lincoln went into power, the Republicans in the federal government and Northerners in general rallied behind the cause of the Union. Further, it was many Northerners opinion that they could not put up with a new slave nation controlling Mississippi River and the West. Many never envisioned the bloody war to come but both sides thought they were right and rejected any claims of a compromise and so took it lightly that they would have to fight for what they believe in. The rebel leaders of the Confederate States believed that states' rights authorized them to dissolve the Union. Again, the federal government disagreed.
The union won the war under Abraham Lincoln who always intended for a compromise but, when the union won the war, ordered for the abolition of slavery.
The process of integrating Europe was slow due to the reluctance of most nations to give up their sovereignty. However, the process accelerated recently the European Union took steps to more closely bring the member states: a free trade zone was formed and eliminated most travel barriers across their borders and a new common currency for Europe, the Euro, was established electronically, initially, in1999.
And states’ rights currently remain a debated topic even today. The use (or non-use) of the death penalty is currently decided by individual states. Other controversial subjects entering the states' rights debate include the authority to allow or disallow euthanasia, the authority to legalize gay marriage, and the authority to legalize medical marijuana, the last of which is in direct disobedience of current official U.S. law. Another concern is the fact that on more than one occasion, the Federal Government has threatened to not give highway funds to states unless state governments pass certain pieces of legislation. But by doing this they upset the balance between the state and Federal governments and for that reason it will be important to solve these issues at the moment and keep the balance of power in equilibrium with both parties satisfied or in the media we will see protests and marches and maybe even more terror attacks due to the anxiety and volatility of the American population.
