Answer: Long before the Union victory, Congress had been preparing for the many challenges the nation would face at war’s end, particularly the integration of four million newly emancipated African Americans into the political life of the nation. Led by the Radical Republicans in the House and Senate, Congress passed the Wade-Davis bill on July 2, 1864—co-sponsored by Senator Benjamin Wade of Ohio and Representative Henry Davis of Maryland—to provide for the admission to representation of rebel states upon meeting certain conditions. Among the conditions was the requirement that 50 percent of white males in the state swear a loyalty oath, and the insistence that the state grant African American men the right to vote. President Lincoln, who had earlier proposed a more modest 10-percent threshold, pocket-vetoed the Wade-Davis bill, stating he was opposed to being “inflexibly committed to any single plan of restoration.” When the 38th Congress came to an end on March 3, 1865, the president and members of Congress had not yet reached an agreement on the terms of Reconstruction. Then, on April 9, General Lee surrendered. Less than a week later President Lincoln was assassinated and Vice President Andrew Johnson, a former senator from Tennessee, became president.

They were of course enraged by the ruling and several political figures and journals vehemently denounced it.

Senator Abraham Lincoln even explicitly stated his grave concerns in his House Divided speech of 1858.
During the 19th century, America had a strong reluctance to become involved in other countries alliances and affairs. Isolationists in America argued that the US had a different philosophy than European countries and the US should defend freedom and democracy by not being involved in such things.
During the Spanish-American War, the US remained isolated and the country fought the war without alliances and without fighting in Europe. But the mindset started to change since the motto of freedom and democracy was substituted by the US bringing an empire in the Caribbean and in the Pacific - the US had influence in the Phillippines, Puerto Rico and Guam -.
President Roosevelt had the big stick policy, he believed that the US should export its values and become a global power. At the same time, he defended that the US should avoid conflicts. President Roosevelt ended the isolationism in the US and started the modern American philosophy of acting aggressively in foreign affairs even without the support of the Congress.
