Israel is quite capable of tearing Hezbollah down by themselves. It all depends upon how they intend to prosecute the war.
Fiddle farting around with surgical strikes and piecemeal ground actions aren’t going to suffice.
The true issue will be, are they prepared to soak up several rounds of hundreds/thousands of rockets from volley’s that will overwhelm their defenses as that strategy was designed to do.
Now, having American assets in the area to assist with intercepting some of those missile barrages is already happening. Prosecuting a war with Hezbollah will require more of those assets, who will then be in harms way and also may be overwhelmed with attacks.
We will see.
Less talk, more action.
