After the u. s refused to fund the aswan dam egypt’s government

This meant that the canal would now be controlled by the government and they planned to use the money earned from traffic going through the canal to finish funding the Aswan dam. This resulted in the Suez crisis in which France, the United Kingdom, and Israel, invaded Egypt. The canal was opened at a later time, but the war kept going on.

Primary sources are usually  more accurate and are written by someone who experienced it or witnessed it. secondary sources are those who heard of it after the fact that can lose details and or twist the event in a light that benefits them.

Ithink it's b . narratives cannot be changed by other historians later
