" Unsurprisingly, Iran used the nuclear deal’s massive financial windfall to fund proxy wars, terrorism, missiles, cyber attacks, and the barbarous Assad regime. Worse, the Obama administration responded slowly as ISIS conquered vast territory, Syria fell into chaos, and Russia reentered the Middle East for the first time since 1973. "
- Bill Hagerty

The quote suggests that Iran took advantage of financial gains from a nuclear deal by channeling funds into activities such as supporting proxy wars, funding terrorist groups, and developing advanced weaponry like missiles and cyber capabilities. Additionally, it points out that during this period, the Obama administration was slow to react as extremist groups like ISIS gained significant territorial control in regions already destabilized by conflicts involving Syria and Russia's re-engagement.

The deeper meaning of the quote highlights the complex geopolitical landscape and the interconnectedness of regional security issues. It critiques the effectiveness of diplomatic negotiations in addressing broader regional challenges, particularly how Iran's newfound economic freedom under a nuclear deal allowed it to pursue aggressive foreign policies that undermined stability in the Middle East. The slow response from the Obama administration is also criticized for not adequately countering these developments, which exacerbated existing conflicts and allowed groups like ISIS to flourish.
