“The march of the flag! In 1789 the flag of the Republic waved over 4,000,000 souls in thirteen states, and their savage territory which stretched to the Mississippi, to Canada, to the Floridas. The timid minds of that day said that no new territory was needed, and, for the hour, they were right. But Jefferson, through whose intellect the centuries marched; Jefferson, who dreamed of Cuba as an American state; Jefferson, the first Imperialist of the Republic--Jefferson acquired that imperial territory which swept from the Mississippi to the mountains, from Texas to the British possessions, and the march of the flag began!” ---Senator Albert Beveridge • What is the main idea?
