what decision did william pitt make that had a significant impact on events after the french and indian war?

he decided to pay militia from the taxes raised by the colonies.
he effected a treaty with the iroquois, changing the balance of war.
he demarcated zones of fighting for each colony, leading to internal conflict.
he decided to pay militia from the british treasury.
he effected a treaty with the spanish, changing the balance of war.

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:

hello no i dont sorry.
