Evidence from multiple sources shows that attacks on U.S. military bases in Iraq/Syria did in fact continue in the months after the January 13, 2024 discussion, rather than ceasing.

• In February 2024, the Syrian Observatory for Human Rights documented 15 rocket and drone attacks on coalition bases hosting U.S. forces in Syria (Al-Omar oil field and Koniko gas field), carried out by Iranian‑backed militias as part of a continued “retaliatory” campaign against U.S. forces amid the Gaza war.

• After the late‑January Tower 22 attack and large U.S. retaliatory strikes from February 2–7, 2024, some reporting noted that Iran‑backed groups halted attacks for a period, particularly in Iraq, as part of an informal truce. (en.wikipedia.org) However, this was a pause, not a permanent end.
• On April 21, 2024, militants fired five rockets from northern Iraq toward the Kharab al‑Jir base in northeast Syria, which houses U.S. and coalition troops. This was described as the first major attack since early February and was explicitly framed by Kataib Hezbollah and allied groups as a resumption of attacks on U.S. forces. (theguardian.com)
• The same "Attacks on US bases" chronology notes further incidents later in 2024, including a kamikaze drone attack on the U.S. Rumalyn Landing Zone in eastern Syria on August 9, 2024, injuring eight U.S. soldiers, and rockets targeting a U.S. airbase in Deir ez‑Zor on August 13, 2024.

Taken together, these incidents show that while there was a temporary lull after heavy U.S. reprisals in early February, attacks on U.S. bases in Syria (and from Iraq into Syria) did indeed continue over the following months, matching Sacks’s prediction that such attacks were likely to continue rather than cease.
