Who is the most powerful leader in the world, Donald Trump or Xi Zinping?

Today at least President Xi Zinping of China looks to be the most powerful leader on the world stage. He has surrounded himself with many of the most unsavoury leaders, including Putin and Kim Jong-un, and is parading his most advanced weapons for all to see. Meanwhile, Trump has sent the mighty US Navy to blast away a small speed boat carrying drugs off Venezuela. The contrast couldn't be more dramatic. I know this is an artificial comparison and it's only today but somehow it seems to sum up how the world is going. Trump was asked whether he should be concerned about China and Russia ganging up on the US and he appeared to be very relaxed about it. He even went on to say how much he liked Xi and thought of him as a friend. But this wasn't the message the Chinese leader was giving as he rolled out new intercontinental ballistic missiles onlow loaders in Tiananman Square. He was definitely making the point that China wants to dominate the world order and push Trump to one side. It didn't help that social media yesterday was full of so-called stories claiming Trump had died. Trump was able to do a Mark Twain and say that reports of his death were premature, and he hadn't succumbed to some deadly illness. Trump is alive and apparently well. But there were no reports of Xi Zinping falling ill. He looked in sparkling health and remains leader of China for life. Again, another dramatic comparison.
