how can you fear a second rate country like iran.

iran has been murdering americans and their allies for decades.

iran was never punished for its wicked ways.

it is time to teach the genocidal shia terror regime a lesson.

israel cannot sacrifice herself for the sake of foreign powers, not
even the united states.

First Israel has the right and even the duty of self-defence, to protect the Israëli people, when being threatened by foreign agression and attacks against Israel, just as any other country has. The/these US officials also should voice concern/should also worry about the "islam" world caliphate, more than 70 countries and a following of almost 2 billion and take the needed measures, sanctions and so on, by the US alone or better together with other countries, to solve that threat and danger, to all of us, on our planet.

only American military can legally exercise 'collateral damage'.

It would appear from this story, the US might be more afraid of Russia's s-300's and s-400's than they make out to be.
Why is the US now countering Israeli strikes that are weeks old? Israel has been grounded as to free flying over Syria with Russia's air defenses now established. It baffles me as to why now the US is crying about strikes by Israel that are old in the news!

While we all wish the absolute best for our troops, if some US generals want ideal conditions including complete safety for overseas deployments - i.e. no hostile activity from the Iranians - they may be better off not deploying, staying @ home...

I am sure the mighty usa can defend itself and has nothing to worry about.

A Second Israel in the Muslim World.

As I have written multiple times, US is a failing empire, and all countries, which are relying on its support must rethink its strategic planning.
The American psychological set up will not allow to quietly draw conclusions from the geopolitical developments and adjust its acting accordingly.
They will try to hold on to the petrodollar scheme as long as possible, disregarding the perils for its own economy and society, as well to the demage it will cause to the rest of the world, including its allies.

Putin is calling the shots.

regime change and has done nothing about it
The Iranians can sense the fear that is apparent in the Americans and this will embolden them to want more blood

It is high time, that Israel can defend itself, independant of/from the US and of any other country. Also of Israel"s police/military/arm weapon-arsenal, in principle, has to be Israëli-made. When the Israëli people are threatened by foreign countries/powers/criminals and terrorists, Israel, just as any other country/people, has the right and even the duty, to serve, to defend and to protect the Israëli people, even outside Israel. Since 1948, Israel is an independant, sovereign entity/country/land/nation and state, with the right of self-determination.
