The US is doing all it can to prevent a war between Israel and Iran's Hezbollah fighters in Lebanon. This move is simply to ensure that if that worst-case scenario takes place, the US is best placed to take immediate action, rather than to lag behind in its response.
While Israel is thankful to the US for ammunition and intelligence sharing, America's policy on Hezbollah — which it considers a terrorist group — is bewildering. Americans need to realize that pushing back the Iran-backed group is essential for Israel's national security — and it's in the US interest as well.
The regional resistance is an essential bulwark against Israel's occupation, as well as Israel's increasing attacks on Lebanon. Iran will continue these important efforts to resist the crimes of the Israeli regime and will not hesitate to escalate its response if Israel does not end its ongoing aggression.
