Sc. 1, lines 50–61: who does macbeth say can set loose these storms?

Macbeth says the witches can set  loose the storms.

In Act 4, Scene 1, Macbeth is speaking to the witches, demanding answers and more prophecies when he says:
"Though you untie the winds and let them fight"
He then provides examples of the damage he knows the storms could do when the witches let the winds loose.

answer: military leaders, supporters of the confederacy and supporters of the union.

explanation:

on november 19, 1863, the speech delivered by president abraham lincoln, known as 'gettysburg address', was intended for politicians, military officials, notable citizens as well as general public, and members of the press who had gathered for the ceremony held in gettysburg, pennsylvania. this ceremony was being celebrated since, in that same year, the battle of gettysburg took place in rural pennsylvania, leaving thousands of men, both union and confederate, killed. lincoln argued about equality within the nation, and the purpose of the war being a "new birth of freedom."on the other hand, there is no relation between lincoln's gettysburg address and his son.
