Was Soleimani an Imminent Threat?

The Trump administration has backed off of the natrative that Soleimani was in Baghdad to plot attacks on four American embassies, but they haven't addressed the imminent threat he truly posed. While it's true the Iranian general can't be credibly linked to the deaths of Americans or a future plot; he is absolutely linked to plotting peace in Yemen without US support, threatening the world empire's dominance in the region.
