To each his own. I am not juding your IQ so dont judge mine, you dont know me so dont get personal. Moreover irrespective of our IQ our discussion are not going to create an addendum to the capabilities of navy or our manufacturing.
You are throwing irrational logic, first your said other countries don't have the capabilities and when I refuted your said we have old tech and thats precisely my point. I never said we can't make steel or others can, if you can't make whats necessary then its nonsense to crib about what we can. Which again answer your second point that we have tech but they are archaic - no one use old stuff in new vessel, unless there are budgetry constrain and that too is not constant and are changed after certain time.
However, your point is way off. We don't have many things which forms the core of shipbuilding as you mentioned, to a point where if not imported we can't make a ship. I'll suggest you read Navy Indigenisation plan 2030, which navy clearly mentions the glaring loopholes that are needed to be curtailed. I am not saying we can't manyfacture its just that we don't have it at present. I am also not saying everything is bunkum all my point is we may have certain point of indigenisation but that shouldnt be the bullying point or bragging right over others. At this point we should be self sufficient in making given the size of our country but we are not. Blame it on shady politics or bogus education but it is what it is.
For layman perspective intrincs like gearbox, shafts, propellors, engine are all imported or license built. I am not even going into advance systems like flight control, radar, weapons etc. In short, we are sort of self sustenance only in making hull and other things like propulsion and radars are out of purview till now. This is coming out of Navy publication and unless you want to disapprove off that, then godspeed. While you are at it also read naval india website on the number of indigenous system kalvari has, it won't be until 5-6th submaine we will reach 50% localisation. Intial 2 ships are almost french/import made.

As far as arihant is concerned its a start and it'll be decades before we can brag about how indigenous it is. On paper, yes its India built but give or take more than 70% of the stuff is Russian, including design, now if you want to call it indigenous then you are welcome.
Before anyone else brag about something else small countries are much better off in shipbuilding then we are. Our ships take anything b/w 8-10y to make where the global avg. is around 4. The reason is arm twisting by countries only because we lack know why and know how. Take a look at Vikrant, if we don't do certain things which pleases russia or israel tehy delay the stuff or put us in a lurch. Had we been sufficient in making generic thing we'd be rolling in IAC1, and P15b much earlier.
In the end if someone else can spoon fed us on tech then same can be applied to Pak and BD, they may have all components imported unlike ours but its nothing they can't achieve atleast manufacturing.
I rest my case.
No jurisdiction, no international law is enforceable. I hope you know that, whether it Int. court of justice, wto or un. You abide by it for the sake of it and it gives a nice impression. It also convey what countries expect from you when you go for bi/multi lateral treaty, your actions speak here. If you flout international rule then people will handle you like that, they may not go for punitive measure but they'd be antsy of you.
A good example in UNCLOS - India had EEZ dispute with Bangladesh and we lost the ICJ appeal. We could have brushed it aside since ICJ verdict is not enforceable but we didn't, we accepted the judgement and handed over EEZ to BD and it gave away a very positive signal that we are here for rule of law and it may bolster our appeal for UNSC PM, unlike south china sea where despite ICJ verdict China keeps bullying and flouting rule.
You can see the whole world getting antsy with China, sure they can't just put sanctions on it but everyone is extra cautious on its intentions and how they flout rules and sooner or later it'll lead to a bigger fallout.
