Does Kamala Harris have steel in her bones?

Nobody sensible wants Donald Trump back in the Oval Office but if Kamala Harris is going to be the next president does she have and will she have the steel in her make-up to fight the world's crises and win? I always thought, despite her unpopularity in many parts of the US, that Hillary Clinton would have been a tough president. I've seen her at work and knew instinctively that she would be capable of dealing with the most obdurate of male international leaders. She was and is a tough cookie. Can one describe Kamala Harris as a tough cookie? I sincerely hope so because what she will have in her in-tray hardly bears thinking about. To name but a few: a nuclear-armed Iran, a Chinese invasion of Taiwan, a major war in the Middle East (if it doesn't happen in the next few days), a ballistic missile attack on the US from North Korea, the launch of an orbiting nuclear device in space by China. All of these things could happen in the next four or five years. How would Harris and her good-natured schoolteacher vice president cope with any of these, let alone all of them at the same time? Her three and a half years as vice president should, one hopes, have given her the steel and backbone to handle such crises. If there is any doubt about it in the mind of the American voters, I fear they might turn to Donald Trump.
