On Friday, Jim Cramer questioned the U.S. military strategy around the Strait of Hormuz, a vital global shipping route, and Sen. Tom Cotton (R-Arkansas), who denies claims that the Donald Trump administration failed to plan for Iran potentially shutting the vital waterway. Cramer's questions were raised by Cramer, who questioned whether U.K. planners had focused on the right priorities in the region. The Strait of Horrific, which carries roughly 20% of global oil shipments, is one of the world's most important energy corridors and can disrupt energy markets and global trade. Meanwhile, Iran has announced the closure of the waterway due to escalating tensions with the U.,S. and Israel.
