The National Defense Authorization Act, or NDAA, passed Congress last week. The Democratic-controlled US Senate approved the legislation with a strong bipartisan majority of 87 to 13 while the House of Representatives voted in favour 310 to 118.

The bill, one of the few major pieces of legislation Congress passes every year, governs everything from pay raises for service members and purchases of ships and aircraft to policies such as support for foreign partners like Taiwan.

The act, nearly 3,100 pages long, called for a 5.2% pay raise for service members and increased the US’ total national security budget by about 3% to US$886 billion. It also lists certain Chinese battery companies that it says are ineligible for the US defence department’s procurement.

The fiscal 2024 NDAA also includes a four-month extension of a disputed domestic surveillance authority, giving lawmakers more time to either reform or keep the programme, known as Section 702 of the Foreign Intelligence Surveillance Act.

That provision faced objections in both the Senate and the House, but not enough to derail the bill.

The bill extends one measure to help Ukraine, the Ukraine Security Assistance Initiative, through the end of 2026, authorising US$300 million for the programme in the fiscal year ending Sept 30, 2024, and the next one.

However, that figure is small compared to the US$61 billion that Biden had asked Congress to approve to help Kyiv combat a Russian invasion that began in February 2022. Republicans had refused to approve assistance for Ukraine without Democrats agreeing to a significant toughening of immigration law.
