Jihad's origin as an arabic term comes from Bedouin raids against rival tribes that predates the Quran. It is used many times in the Quran purely in the context of expansionary war and combat against nonbelievers. It is clearly not just an internal struggle.
Again you...
a) Try to morph what was said which was "to struggle" to a limited definition of to "internal struggle".
b) people fighting or using that word before the Quran is common knowledge as it is a Arabic term and conflict and wars in the Arabian peninsula predated Muhammad.
Rather the use of the word was refined and completed with the Quran as were a ton of other Arabic words and grammar.
c) The Quran uses it to refer to struggle and if applied to warfare as a struggle against said people to whom you are in combat against.
Clash of ideals or even clash against one's desires and self control goes under this umbrella as well.
Basically you can also use the word in the context of self defense (and before you use verses without actually knowing its context and/or cherry picking it out of a large narrations with before and after verses).
You can twist and turn the meaning, you can narrow it down to mean only one thing and not the others but reality stays the same. The origin of a word from a action is not only common for Arabic but a ton of other languages as well. It evolved towards its final form but the origin of it was still the same. Those Bedouins created it prior to showcase a struggle of their clan against another, via rivalry, war, or even revenge.
You assumptions will only please people who wish to believe what they want to believe it doesn't in anyway change the actually real meaning when all is said and done.
I just provided you with the truth and reality if you can't accept it then it is on you and not me since in the end you can only correct yourself.
You are narrowing down something too broad and thinning it down to only mean one thing when clearly it isn't
You can't have a struggle if there is literally nothing to struggle against.
Jihad itself can have secular connotation as well as Islamic connotation, each of which follow a set of rules and branches. None of which just toss it into only war and nothing else with no meaning or any reason as to why.
If it goes to the context of war however then you break it to either a Secular context or an Islamic one to each have their own rulings and engagement.
Again when you enter combat Jihad for Islamic conditions then Islamic rulings take place which are these

Don't try and twist things into some narrow margin then come and reply at me with ridiculous agenda based reasoning
Your info can fool people who are ignorant and relay on agenda based propaganda from some alt right source but someone who actually knows what they are talking about?
The only thing you can do is change what I said.
