World leaders should have the ability to do business in a cold-blooded manner, putting aside grievances and slights.
And even if you think that Trump should retaliate against those he thinks have done him wrong, he could’ve attacked Netanyahu over two years ago. When Israel is facing world-wide criticism and persecution is not the time to do it.
“World leaders should have the ability to do business in a cold-blooded manner”
No, they should have a reputation for honesty and straight talk. At the moment that “real world” approach is why only a fool takes the word of the US Government. That is at home or around the world.
The world is full of governments that run like the British. Sneaky, lying, secret deals, hidden agendas, etc. Just as with individuals, the best way to deal with such people is to have hard uncompromising principles and in public.
Tolerating a little dishonesty in government is like tolerating a small leak in your hot water heater.
The government of liars and sneaks is always inflicted on it’s own people. The secret government mentality focused outward is what directly lead to the 2020 election being a complete fraud.
