The Israeli government has de facto control of large sections of the Palestinian Territories. The people in those territories, however cannot participate in the elections of that government.

The distinction being de jure and de facto control is something worth debating, but it’s trivially true that Israel controls large swaths of territory where people are not eligible to participate in that government.

Consider the meanings of the following words:

- sovereignty

- border

- population

In that order, in the context of that region. Then consider their meanings in the context of (say) Canada. Consider how conventional applications of those terms are different for the two.
