The incident occurred shortly after Charles had completed a state visit to the US that began just two days after a shooting at the White House Correspondents' dinner. Charles later remarked that a charging bull elephant was more alarming than the incident, describing it as 'a bit silly', according to the Daily Express. Pauline Maclaran, a professor and co-author of Royal Fever, told the Daily Express that Charles was described as 'cool as a cucumber' and his handling was admired.
She said the 1994 incident does not influence the current state visit to the US, and noted that the 1994 situation was designed to scare, not harm, while current threats are more real, especially for those around Trump. The motive for David Kang's actions remains unclear, and details of the security response have not been disclosed.
At the time the prince was described as being 'cool as a cucumber,' a very British expression I think!
But certainly he didn't panic and his handling of the situation was much admired.
I think there is little comparison with the previous situation which was designed to scare him but was never intended to harm.
This time there is more of a real threat, although not necessarily to the King and Queen, but rather to those around Trump.
