Go and check the history of Trump, especially during his second term as president. Trump has implemented everything that he says. From the tariff war to the capturing of Maduro and don't forget the military actions on Nigeria as he throw some bombs there and is likely to revisit the Nigerian case again after this war on Iran and finally we are all seeing what is happening presently on the middle east. Trump has go ahead to implement threats so trump will resume his attack on Iran after these peace talks ends.
Why did you mention Nigeria? Know that there is nothing good that Trump wants to do in Nigeria. You should learn how to do your country good by yourselves, America will not be in Nigeria to help you than to take from you. Nigeria issue is very complicated than the help the United States will provide.
Just to mentioned, Trump is not going to revisit any bombing in Nigeria after the war man, we have to face our problem ourselves, the Nigeria government should be held responsible for whatever security threats we are facing within our country, calling on or depending on another country president to come and solve our problem won't work out in our favour rather it exposes our military weakness to the world.
You most also know that, this war is a inter continental anti-ballistic missile war, it one thing to say, and another thing to be able to afford both the cost and consequences of the action, world leaders like Trump knows better and how to play around with his worlds and actions.
