Pakistan's JF-17 Thunder fighter is gaining export momentum that is now squeezing India's homegrown Tejas out of the same markets, Defence Security Asia reports. Two rival suppliers hoping to sell affordable fighters to the same non-aligned buyers are undercutting each other for the same contracts.

India's deeper problem is structural. Its 'Atmanirbhar Bharat' self-reliance drive means it now buys more hardware at home, yet its arsenal still leans heavily on imports, IndraStra Global reports. India remains both an aspiring arms exporter and one of the world's largest arms importers.

Britain is tightening the terms on which outsiders can sell into its own market: a new UK defense policy now requires overseas contractors to invest locally as a condition of doing business, ADS Advance reports — the kind of offset demand that lets importing states extract technology and jobs from suppliers.

Southeast Asia is chasing the same goal from the buyer's side. ASEAN states are racing to build sovereign defense industries of their own rather than stay dependent importers, Army Technology notes.

Hypothesis: these are not four separate stories but one — rearmament is splitting the arms trade into self-interested blocs rather than uniting allies. Supporting this: Pakistan and India are rival exporters fighting over the same buyers; Britain's mandate protects its own industry even against partners it otherwise arms jointly; ASEAN's build-out is explicitly meant to need fewer foreign suppliers. Against this: all four could just be ordinary capacity-building and diversification inside a still-intact Western-aligned system — more suppliers and local content do not automatically weaken alliances.

What to watch: whether Tejas can still win orders against a cheaper JF-17, and whether ASEAN's new manufacturers end up supplying each other — or new foreign patrons.
