You really think the 14th amendment would apply to the founding fathers? You are trying to use a general definition and while you are technically correct, it is also completely irrelevant.
The issue facing Trump is insurrection against the USA, not against a foreign country. The founding fathers didn't commit insurrection against the USA.
Let me reference the 14th amendment for you so you understand why this is an issue and why your dictionary definition is inapplicable.
https://constitution.congress.gov/browse/amendment-14/section-3/
"No person shall be a Senator or Representative in Congress, or elector of President and Vice-President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any State legislature, or as an executive or judicial officer of any State, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. But Congress may by a vote of two-thirds of each House, remove such disability."
In other words, Trump shall not be a President (of the USA) if he committed insurrection against the USA unless congress votes by 2/3rds to override.
Apples and oranges.
No, you're trying to argue a distinction that doesn't have a difference.
insurrection has a purpose: "to defeat their government and take control of their country"
If the insurrectionists succeed in their purpose, then, by definition, the government they rebelled against may or may not still exist as it was before. However, the insurrectionists will have taken control of their country.
And why do you think our founders committed insurrection against a foreign country? Are you that ignorant of the birth of the US. We began as 13 British colonies, and the government of the colonies was the British Monarchy. The government our founders pushed back against was not "foreign." It was our own government -- as colonists under British rule.
No different than Canada. They are a Constitutional Monarchy, and although they have control over most of their country's affairs, Britain still controls their foreign policy.
I guess you'd call Great Britain a "foreign counrty" to Canada, too? You'd be wrong.
Country can be defined as a nation or state, a land, or a people. Be careful how you use 'country' in your arguments.
