First of all, you must understand that weapons manufacturing is a business of disposable goods. It is an industry which requires the destruction of what it produces, so that it can replace what it destroyed.
You may have noticed that when the US was winding down their occupation of Afghanistan they simply destroyed their unused arms and equipment; they did not gather it up in order to use it elsewhere. Whatever the Taliban had not destroyed, they destroyed it themselves; because it is necessary to destroy it before you can get paid to replace it.
This is obvious if you monitor the share prices of companies like Raytheon, Lockheed, General Dynamics and so forth; their profits are built upon the use and exhaustion of what they manufacture, to keep conflict zones constantly replenished. Military conflict is the single greatest mechanism for maintaining profitability, and the single greatest way to maintain the status quo of the power structure.
When you destroy a tank or a helicopter, you participate in the profit-making system and send a message to the global owners of capital that, for instance, Sisi is an asset to their profitability. His rule guarantees constant demand for their products.
Your action does not inflict loss, it ensures profit, and it solidifies international support for the regime, because the nature of your strategy guarantees the regime’s endless dependency, while not interfering with the real power structure in any way. It is ideal for business, which is why a survey of World Bank representatives showed that those living in conflict zones all felt that the economic conditions in their respective countries were moving in a positive direction. There is absolutely no incentive to settle conflicts in which the primary targets are soldiers and their equipment.
It is remarkably short-sighted to say that you must destroy the weapons of your enemies because those weapons are being used to kill Muslims; as though there is a finite supply of weapons. This is a strategy for prolonging, not winning the conflict.
The way that you defend the Muslims is by inflicting unbearable consequences against those who attack them, not by affirming the profitability of killing Muslms.
Unless and until you make oppression and injustice unprofitable, it will continue. It is a very simple equation. Military conflict is highly profitable.
Targeting multinational corporations and investments disrupts profitability and inflicts loss on the controllers of conflict, which is the only way to bring the conflict to a successful conclusion.
