If Iran tries to fight a low-level fight, we are ready, too:
One of the Navy’s oldest transport ships, now converted into one of its newest platforms for warfare, arrived in waters off Bahrain late last week, a major addition to the enlarged presence of American forces in the Persian Gulf designed as a counter to Iran.
I've mentioned the Ponce development. Click through for a link about the last time we were involved in a low-level duel with the Iranians over freedom of navigation in the Persian Gulf.
I wouldn't discount Iran's ability to hurt us. Respect them in that regard.
But don't discount our ability to take whatever Iran tries to dish out and pound them into the ground in return.
