Bismarck was extremely contemptuous and dissatisfied with the "constitutional unity" of the bourgeoisie. He doesn't believe that any article in the Constitution will have the power to make people super-living. He said: "If we really succeed in winning a unified German motherland according to this new and ongoing road ... then I may express my gratitude to the founder of this new national order; But now for us, this is impossible! " Therefore, he hit the nail on the head and pointed out, "I am sure that Prussia's honor does not depend on playing Don Quixote everywhere in Germany for those famous people who are sick in parliament." "The reunification of Germany and the right to make a report in the forum of parliament are not the same kind of problems." Bismarck said contemptuously, "A parliament is easier to be mobilized than an army." "It is impossible to judge these principles by a majority of 11 votes through parliamentary debate." Of course, Bismarck not only regarded constitutional unity as useless, but also was sensitive to the harm of parliamentary constitutionalism to Junker's rule in Prussia. In his view, the parliamentary democratic political thought is always a threat that the barricade fighters may master the sovereignty, saying, "This may spread the poison of democratic politics into disciplined Prussia."

Bismarck strongly advocated: "The decision on this (Germany) issue is not made in our parliament at all, but in diplomacy and the battlefield", and the reunification of Germany "can only be achieved by waging war with the opponents." Therefore, he always regards a country's military strength as the factor that determines the value of this country, and strongly advocates the establishment of a strong armed force. He thinks: "Without the Prussian army and a strong Prussian army, the concept of the German nation will not be realized at all." A linguist named Mark Mailer once complained to Bismarck: "Now every European is a soldier, and we even live in prehistoric times like beasts. ..... If on the European continent, a country will feel very unsafe without many cannons, then what should it say as a neighboring country? " In this regard, Bismarck only said one sentence: "Vague humanitarianism!" This "strong Junker" who has long been determined to "take pleasure in training the blade of the army knife for new recruits" is determined to cure Germany's decline and cowardice with fire or knife.

on September 3, 1862, a week after he became prime minister, he attended a meeting of the parliamentary budget Committee (only more than 2 members attended). A draft resolution on the appropriation in 1863 was discussed at the meeting. At the beginning of his speech, Bismarck also expressed in a gentle tone how much he attached importance to the government and parliament working together to solve the budget problem. Then, he changed the subject and put forward his basic views on solving the German problem directly: "Prussia must accumulate its own strength and hold it in its hands for a favorable opportunity." "This opportunity has been missed several times. Prussia's national boundaries stipulated in the Vienna Treaty are not conducive to sound national life. The major contemporary problems cannot be solved by speeches and majority resolutions-this is the mistake made in 1848 and 1849-but by iron and blood. " This is the so-called "iron-blooded policy" summarized by later generations, and Bismarck was named "iron-blooded prime minister" for this reason.

In the "Iron Blood" speech delivered in Parliament, Bismarck originally thought that he only told the facts of political life. However, it caused a public outcry. The whole cabinet, except for Secretary of the Army Ron, has no cabinet member to support him. Even Pu Wang, who used him, was deeply worried at this time, and once thought: Should Bismarck be dismissed before he could cause more losses to the court? On October 5, when William I met Bismarck on his way back from Baden to Berlin, he said with regret, "I can totally foresee how all this will end." "In front of the Opera Square, under my window, they will cut off your head and cut off my head later." King Pu pessimistically compared Bismarck and himself to the Earl of Stratford and Charles I in England.

Faced with layers of resistance and heavy obstacles, Bismarck did not flinch. There is no other way but to struggle. He persuaded King Pu: "Can we die more honorably?" "I am fighting for my king's career and your majesty." Bismarck finally eliminated William I's inner reservations with his firm and courageous attitude, and formally confirmed Bismarck's original temporary appointment.

So Bismarck boldly waved the weapon of "blood and iron" and carried out the policy of "military power".
