Waltz, a Green Beret veteran who served in Afghanistan, the Middle East, and Africa, won't require Senate confirmation, and will step right in the middle of Trump's vow to end the wars in Ukraine and the Middle East.

In September of 2023, Waltz said in a Fox News op-ed, "The era of Ukraine's blank check from Congress is over," suggesting that future aid packages should have accountability and ensure strategic use of resources.

Waltz also pushed for US allies to pay their fair share.

We need this administration to bring our allies to meet their pledge to spend at least 2% of their GDP on defense now, today. Unfortunately, Biden's diplomacy seems to be lagging. The largest European states consistently fail to meet that benchmark, pledged at the 2014 NATO summit in Wales shortly after Russia's last Ukraine invasion.  

Germany, the largest economy in Europe and the most pivotal balancer to Russia, pulled back at the last minute from enshrining the two percent annual commitment into law. That needs to change – the administration cannot expect American taxpayers to pay for European security indefinitely.
