The short answer to why both the Biden and Obama administrations failed to achieve peace in the Middle East is that they took actions opposite to President Donald Trump’s current efforts, which have led to a ceasefire.

The radical Islamic world of the Middle East was convinced that Israel would be doomed eventually.
Yet both Democratic administrations let Iran profit from oil sales.
