Answer :
"It reflected Egypt’s willingness to work with the Soviet Union" is the best answer as to the best description of why Egypt’s purchase of weapons from the Soviet Union was significant.
It reflected Egypt’s willingness to work with the Soviet Union
The purchase of weapons from Soviet Russia was a decision made by the Egyptian leader, Nasser, in order to collaborate with the socialist world. Many Geopolitical thought points to the fact that the creation of the state of Israel in 1945 was a key point for the formation of military alliances between Arab states and the Socialist bloc. The willingness to collaborate with the Soviet Union from Egypt is the counterpart to the cooperation from the recently created Israel state with the US and the West.
The purchase of Soviet equipment and weapons is also a consequence of the failed policy between the US and the Arabic state to conciliate regional interests.
