You can't win a ground war against people who consider it a good thing to die killing Americans. What you are fighting is a religious ideology.
That element would continue even without a country.
The only thing thay can be done is to destroy the regime, install another, and deal with the continued terrorists.
The only way you can destroy the regime is to put boots on the ground. I agree we would be fighting a religious ideology just as were did in Afghanistan and Iraq. Our military presence in both those countries brought other Islamic extremist organizations to both those countries to fight against us. The same would occur if we put boots on the ground.
You also have to think about what would happen if we did achieve that goal and Trump put in a new government, so he could control them. Think about Venezuela now. Look at the justification he gave using our Navy to destroy drug running boats. "They're bringing fentanyl into our country." Then he started talking about the evil regime in Venezuela sponsoring the fentanyl and they had to be taken out of power.
Then that led into him telling the world that the country had an election and the people who actually won, weren't allowed to take their seats because the regime wanted to remain in power. Trump said he wanted to take that regime out of power so the people who actually won could take their place. Did that happen? No. After taking Maduro and his wife into custody, he allowed those in the regime to remain in power. Why? He said it himself. The regime was cooperating, doing everything he wanted them to do. The real reason for the invasion of Venezuela had nothing to do with fentanyl, it was about the oil.
There were no nukes in Iran. There couldn't have been if he were telling the truth in June of last year when he said our military obliterated the three nuclear enrichment sites. He said it would be years and years before they could ever start again. Look at the reason he gave for using our military again in February through now. Were they really a couple of weeks away from having a nuke and a month away from using it to destroy Israel and the Middle East as he claimed? I don't buy it.
I think the reasons was to take out the regime and replace it with a puppet government who would do everything Trump wanted so that we could control the oil and the strait.
You may think Trump has all the cards, but that's not the case. Iran does. Remember our missile arsenal is now near empty and this war is very unpopular with the majority of voters. The economy is not good because the high gas prices have increased the cost of consumer goods. Polls show the Democrats have the edge when it comes to who gets the majority of the House following the November general election. Polls are also showing the majority believe the Republicans are doing a poor job handling the economy. Control of the Senate is a toss up. Contrary to Trump's claim his approval ratings are the highest they've ever been, they're actually very low.
If he puts boots on the ground, the Republicans will lose the House for sure and most likely the Senate. Now can you see why Iran is the one holding the cards?
