That's when one has morons under Persian Shia Iranian Ayatollah led leadership hell bent on religion sectarian supremacy presume - that it's about costs, & worse - WITHOUT looking at the big picture.
Let's just take a simple example of the 1st ship that the Shia Persian Iranian led Houthis had HORRIFICALLY hijacked - an innocent trading ship on open seas - the Japanese logistic managed Galaxy Leader.
That ship was a car cargo vessel, with at the least 6,000 cars that were meant to be shipped Worldwide, not just to Israel alone. Each car costs at the minimum at Open Market Value of $15,000, let alone EU luxury cars that cost FAR more. Based on that average, that ship was carrying $90,000,000 ($90 Million) worth of cargo - manufactured & paid in advance by HONEST & INNOCENT traders & consumers.
Furthermore, with it's BLATANT PIRACY UPON HIGH OPEN SEAS, NO Nation had step in to helped Biz & Consumers, whom only saw their biz costs rise UNNCESSARY thru various means to find more longer costly shipping routes to send cargoes, often at high costs passed on to end consumers, est in BILLION$, & TRILLIONS annually, which are far more than the cost of missiles that CAN ANNIHILATE the sick minded Shia Iranian minded led Houthis rebels. And the monstrous hijacking of a mere cargo vessel is NOT the only incident in that open sea. Many more had been harmed & even bombed at.
Thus should such atrocities to Humanity & trade be allowed to continue? Only the courageous & ELECTED PrezTrump had done so, but sadly often without support from other nations whom would rather live on knees than to stand up to fight for Humankind's survival & progress.....
