The Netherlands has made history by becoming the first NATO member to act under a new initiative to supply Ukraine with American-made weapons. On Monday, Dutch officials announced a €500 million package of US military equipment and confirmed they will send it to Ukraine.

The Netherlands said on Monday it will contribute 500 million euros ($578 million) to purchase U.S. military equipment for Ukraine, becoming the first NATO country to contribute to a new mechanism to supply Kyiv with American weapons.

Part of the agreement involves a commitment to buy American oil and gas. Over the course of the Russia-Ukraine war, now in its fourth year, most of the EU has slashed its dependence on unreliable energy supplies from Russia, but Hungary and Slovakia still have not.
