Did The Prophet ﷺ Order Assassinations?

Logical reason of such orders
​
Madinah was the state with Muslims as its nation and Prophet Muhammad ﷻ as the head or president of that state. In those days poetry was a strong culture trait of the Arabs. It was recited at moments of lamentation if on anyone's death, at the joyous ceremony of someones birth or marriage. Poetry was used to incite the emotions of listeners at moments of sadness and joy. Likewise it was also recite by skilled poets to incite emotions of hatred and fighting against an enemy. Since the enemies among the pagans and Jews left no stone unturned in their attempts to harm the Prophet and his followers, they even resorted to poetry to incite war against the Muslims and such poets were threat to the security because their poetry lead towards battles and even assassination attempts at the Prophet himself. 

Any attempts through poetry to incite enemies of the state that could jeopardize their security, endanger the lives of its population and have its leader killed eventually destabilizing the state, was considered an attack on the state. These people did not only spew hatred in their poetry but also conspired and financially supported to kill the head of the Madinah state i.e. Prophet Muhammad ﷺ. Such acts could not only weaken the foundation of this nation but also impede the mission given by Allah ﷻ to his Prophet. Such acts were not committed against the Prophet’s own person they were in fact committed against a whole community. These sorts of acts if allowed to slip by the Muslim leadership could have caused a gradual disintegration of their state. Being a leader, it was the Prophet’s responsibility to secure the state and its people. Therefore, it was necessary for the Prophet to order his companions to assassinate such persons. To understand better, let take the example of some terrorists planning to assassinate the President of a country, and killed many innocent in their attempts. However, before they could achieve their target of assassination, the law enforcement of that country succeeded in catching them. Once caught, what do you think would happen to these criminals? Their recompense would be the same as those conspiring poets at the time of Prophet Muhammad ﷺ.
