The Senate Republicans aligned themselves largely behind the management of President Donald Trump about the conflict between Iran and Israel and said they trusted Trump’s trial about whether the United States should involve himself.
Trump said again on Wednesday that he has not decided if the United States should get involved more in which he pointed to journalists that he would decide at the last moment, stating that he would make the decision “a second before.”
The question of getting more involved in the conflict has divided Trump’s magic base, and some point to their campaign promise to keep the United States out of foreign wars.
Senator Lindsey Graham, a defense hawk that said he spoke with Trump last night, supported the use of force if diplomatic efforts fail.
“Either you want them to have a nuclear weapon, or not,” said Graham. “And if you don’t, if diplomacy fails, you use strength.”
Most Republicans said they agreed with Trump that Iran can’t have a nuclear weapon.

“I think this is something that everyone can agree on: Iran cannot have a nuclear weapon, or the ability to deliver a nuclear eye, point,” Senator John Kennedy said.
“American foreign policy is always a balance between … between values and interests. The value here is obvious to all. Iran cannot have a bomb. It is simply unthinkable and support to the president unconditionally about that,” said Kennedy.
Senator Mike Rounds said there is evidence that Iran was approaching to build a nuclear weapon.
“If Israel has a plan that is appropriate to solve the problem, then we do not need to be there, but we should never take or eliminate the options that are available to the president to exercise his authority as a commander in chief,” Rounds said.

Senator Kevin Cramer said he would support Trump’s decision if he decided to enter the conflict, but would also support the decision to “help Israel do the job.”
“Iran has really made that clear. They promised to eliminate the United States of America. I prefer not to let them get here,” Cramer said. “I prefer the preventive prevention of war instead of having to finish one after it reaches our ground, right?”
Cramer said Trump has been handling the crisis “brilliantly” and applauded Trump’s suggestion that he may or may not get involved.
“I think it’s quite honest, right? I can or may not. I think that element of surprise, so to speak, it remains with an answer that does not tell you what it is going to do,” he said. “It would be crazy for the president to give a warning, if you want, what you can do.”

Both Republicans and Democrats said they would like Congress to have a role in determining whether the United States gets involved in the conflict, but the Republicans were much less blunt.
“I would love that Congress have a role, but we certainly do not have time in the midst of what we all see that Congress feels and coexists for six or eight months,” Kennedy said.
The Democrats, on the other hand, said Trump should obtain the approval of Congress before taking any military action.
“At some point, the president must come to Congress if there will be an active kinetic military participation that constitutes the war. That is the Constitution, said Senator Richard Blumenthal.” And I believe that the president must face responsibility at some point, for the use of military force in combat, in a war. And the question is, when that point is. “
Other Democrats said that the United States should be trying to climb the conflict instead of inflaming it.
“We do not need to climb in Iran. That does not make anyone in the Middle East safer, and certainly does not make the United States safer at this time, Senator Elizabeth Warren said.” The role of the United States should be to help descalize, to boost negotiations, not try to put more things in a row. “
