Claim
After decades of work, the Panama Canal was completed, which connected the Atlantic and Pacific oceans in 1913 and greatly facilitated global shipping navigation.
Correction

The Panama Canal officially opened to shipping on August 15, 1914—not in 1913.

Full reasoning
Reliable historical references date the canal’s opening/completion to **1914**: - **U.S. Census Bureau**: “the United States officially opened the Panama Canal to shipping traffic on **August 15, 1914**.” - **HISTORY.com** (A&E): “On **August 15, 1914**, the Panama Canal was opened to traffic.” So the statement that the canal connected the Atlantic and Pacific “in **1913**” is off by about a year; the widely cited opening date is 1914.

Claim
In 2018, the NAFTA was replaced by the [U.S.–Mexico–Canada Agreement (USMCA)](/wiki/U.S.%E2%80%93Mexico%E2%80%93Canada_Agreement "U.S.–Mexico–Canada Agreement").
Correction

NAFTA was replaced when USMCA entered into force on July 1, 2020 (it was signed in 2018, but didn’t replace NAFTA then).

Full reasoning
It’s true that the USMCA was **signed in 2018**, but it **did not replace NAFTA in 2018**. The replacement happened when the USMCA **entered into force**. The U.S. Trade Representative (USTR) states explicitly that the **USMCA entered into force on July 1, 2020**, and that it **replaced NAFTA** at that time. Therefore, saying NAFTA “was replaced” in **2018** is incorrect (the correct year for replacement/entry into force is **2020**).
