If Montesquieu were alive today, how might he feel about the effectiveness of the separation of powers in limiting government power? (1-2 sentences)

Montesquieu argued for the separation of powers to prevent the concentration of power in one branch of government and to ensure checks and balances between different branches.

In the founding of the US government, the principle of separation of powers was incorporated into the Constitution, with the legislative, executive, and judicial powers divided among three branches to prevent tyranny.

If Montesquieu were alive today, he might feel that the separation of powers has been somewhat effective in limiting government power, but might also be concerned about possible erosion of this principle due to the increasing executive power and political polarization.
