Despite having been to Cyprus found there was little evidence or mention of the division,which is also religiously (Orthodox cf. Islam) as well as nationality-based.
Though others probably know far better and to the legitimacy of any Turkish claim, other than just its proximity.
As for India and its 'sub-continent', that's an extremely complex case. Suffice to say that India itself is an amalgamation of 28 smaller countries, now based around an official federation.
The creation of Bangladesh and Pakistan, as you say aren't exactly foolproof as there's still at least a mere 100 million + Muslims in India.
Certainly with Pakistan, it was based on areas where Muslims had a majority but still divided whole states like Gujarat which doesn't sit comfortably personally.
Also would like to see an independent Kashmir, but even assuming India & Pakistan would let this happen, how would any small country feel being a buffer between two nuclear armed nations.
Much of the current situation though was due to past colonization (& then the usual ruthless 'divide-and-rule' policy based on things like religion, of the hapless locals) by the usual suspects.
So at least countries like India and Ireland have a shared experience in this respect.
