Why don't you impeach Trump ?

Hello, I would like to understand what prevents Trump's impeachment. From an outside perspective, it is clear that he has been manipulating financial markets since his election to enrich himself and his relatives (he makes no secret of this), is accused of rape of minors, and he alone decides to launch a war with Iran on Israel's behalf. Isn't that enough to impeach him? Is it impossible to prevent it from continuing to harm the entire planet?

Thank you for your answers.
