What is a strength of the executive branch?

Answer 1

In the US, the power of the executive branch of government has been growing. This impacts both foreign and domestic affairs. For example, the US president signed a executive order to create a set of policies that allows Iran to make certain limited progress in nuclear physics in return for the unfreezing of assets mandated by violating UN resolutions. The US Congress opposed this so-called treaty but did not have enough votes to overturn the treaty with Iran. In years past, a US president seldom made foreign treaties or agreements without the support of the US Congress, specifically the US Senate. Executive power may be reaching a point of critical mass however.
