US President Joe Biden, along with his top advisers, is cautioning the Israeli Occupation with increasing urgency that pursuing military objectives in the Gaza Strip will become more and more challenging as global concern grows over the humanitarian crisis there.

Biden, along with Defense Secretary Lloyd Austin and Secretary of State Antony Blinken, who just arrived in Jordan, have conveyed their concerns, including diminishing international support, in recent private conversations with Israeli Occupation officials, according to CNN.

Behind the scenes, US officials believe there is a small window for the Israeli Occupation to achieve its stated goal of neutralizing Hamas before the outcry over humanitarian suffering, civilian casualties and ceasefire, gets to a 'tipping point.'

Some of Biden's close advisers believe that it is a matter of weeks until resisting pressure to publicly call for a ceasefire becomes unsustainable for the American government, as sources informed CNN.

This comes as the Israeli Occupation's aggression on Gaza is going full force with no signs of slowing things down.

What was considered particularly troubling to Biden, along with his national security team, were the airstrikes targeting a refugee camp.

According to the CNN, a source said th at Biden "didn't like this at all."

Officials insisted that Biden has not set 'specific red lines' for the Israeli Occupation, which has to this point also included a ceasefire.

In a call with Netanyahu Sunday, US President voiced his concern about the surge in violence against Palestinians, insisting that these attacks must cease, according to a source familiar with the conversation and CNN.

Biden and other US officials have also increased their calls for a 'humanitarian pauses' to allow captives held to leave Gaza and for aid to enter the Strip. Additionally, they called for maintaining phone and internet connectivity, as well as allowing fuel and water into the Strip, CNN reported.

Netanyahu rejected some of these calls saying they wouldn't do so unless Hamas released all captives.
