Pakistan could buy the F-16s. Congress made them $430 million dearer.

Washington still permitted the eight-aircraft sale, but Congress blocked US financing, leaving Pakistan to find roughly $430 million more. Nothing was embargoed; the economics were transformed.

Political control over finance can kill a defence purchase without prohibiting it. Permission to buy is not much of a concession when the funding structure that made the deal possible disappears.

This is the part the brochure is unlikely to discuss. An approved budget is assumed to remain available until the capability arrives. The actual control sits in legislative votes, subsidies, sanctions, payment channels, foreign exchange and the conditions attached to public financing. That is the control point hiding behind the headline fact: Pakistan could buy the F-16s.

Control is usually exercised through procedure, not a cinematic red switch. The party holding the leverage can leave the sale technically permitted while making its price, financing or payment route impossible. By the time the buyer is certain that the delay is political, the readiness loss has already begun. For Pakistan, the warning is captured by what followed: Congress made them $430 million dearer.

Before selection, put the uncomfortable questions into the procurement file. Which sanctions apply to the buyer, seller, bank or intermediary? Can the contract survive exchange rate and interest rate shocks? What capability is lost first when a payment milestone slips?

Resilience has to be purchased deliberately. The programme should verify every intermediary against current sanctions rules, plan a lawful exit if financing conditions change and stress test the programme without concessional finance. If those items are unfunded, the independence claim is unfunded too.

There is also a timing problem. The alternative supplier, component or service may exist, but it may need qualification, integration, training and fresh political approval. Those months count. A substitute that becomes usable after the crisis is over is not a substitute. It is an explanation for the inquiry that follows. The exercise has a concrete starting point in this case: Pakistan could buy the F-16s.

For Pakistan, the weapon can be approved while the money is vetoed.

The finance ministry should see this risk too. Resilience can look expensive because its cost appears in the tender. Dependence often looks free because its cost appears later, in emergency purchases, redesign work, lost readiness and political concessions. That accounting difference does not make dependence cheaper. It merely hides the invoice. The headline fact, 'Pakistan could buy the F-16s', should carry that exposure in its score.

Cheap finance can make a necessary acquisition possible. It also creates leverage for whoever supplies the subsidy, guarantee or annual appropriation. That distinction matters here: Congress made them $430 million dearer.

The next three questions belong in the operational plan, not an annex. Are alternative banks and currencies legally available, or merely discussed? Is the acquisition affordable without the current subsidy? Who can withhold annual funding after the initial approval? If nobody owns the answer, nobody owns the risk.

The final test for Pakistan is simple: does the capability remain affordable and payable when the subsidy, annual vote or preferred financing route changes? If the honest answer begins with 'provided that somebody else agrees', that condition belongs on the first page of the procurement decision, not in an annex nobody reads.

The buyer may still be allowed to purchase the system and yet be unable to afford, finance or pay for it on the terms that made the decision possible. The weapon may be approved while the money is vetoed. That exposure sits behind the claim that 'Pakistan could buy the F-16s'.
