What difference does it make that the diplomats in an unsafe country were not granted even minimum security even though requested by them?
What difference does it make that Americans under attack were denied even a cursory effort of support?
What difference does it make that four Americans were killed?
What difference does it make that the leader of the regime and Marxist/Progressive party lied to the American people for purely political purposes and continues the lie even though it is now documented to be a lie?
It does make a difference. In a free society, government officials are servants of the people. As servants of the people, these government officials have a duty and obligation to be completely transparent and truthful. In a totalitarian state, government officials are rulers of the people. Transparency and veracity are neither required nor expected.
The leader of the current regime and Marxist/Progressive party promised he would fundamentally transform the United States from a free nation to a totalitarian state. The government official, when asking this question, exhibited the belief this regime now views their role as ruler and not servant.
That is what difference.
