In three short tweets, Trump explained he is done being threatened...

"Iran is talking very boldly about targeting certain USA assets as revenge for our ridding the world of their terrorist leader"

Then reminded his followers just exactly what Soleimani had done...

"[Soleimani] had just killed an American, & badly wounded many others, not to mention all of the people he had killed over his lifetime, including recently hundreds of Iranian protesters.

He was already attacking our Embassy, and preparing for additional hits in other locations. Iran has been nothing but problems for many years."

Then came the warning:

"Let this serve as a WARNING that if Iran strikes any Americans, or American assets, we have targeted 52 Iranian sites (representing the 52 American hostages taken by Iran many years ago), some at a very high level & important to Iran &  the Iranian culture, and those targets, and Iran itself, WILL BE HIT VERY FAST AND VERY HARD. The USA wants no more threats!"
