> The US is making an absolute mockery over the honor and responsibility etc.

The US was a rather empire without many scruples before WW2 and after it. It engaged in genocide in Vietnam, and was complicit in several others, including the ongoing one in Gaza - which was sanctioned, funded and facilitated first and foremost by the Biden-Harris administration.

So, without detracting from Trump's crimes and jingoist rhetoric and action, his deviation from US foreign policy tradition is not as far as one might imagine.
