How did sam houston persuade the united states to annex texas? by claiming that texas would rejoin mexico to settle its debts by threatening to ask france for if the united states refused by threatening to ask britain for if the united states refused by starting a border dispute with mexico to gain new territory

The correct answer is "by threatening to ask Britain for help if the united states refused".

The Republic of Texas, with Sam Houston as President, declared Independence over Mexico on March 2, 1836. Houston was supportive of the idea of annexing with the United States. However, there was major reluctance to do so in the US government, as Texas was a slave-holding state and abolitionist reforms where being discussed.

Sam Houston would later enter negotiations with Mexico in order to secure official recognition from that country. Great Britain was the mediator in those talks.

After learning this and fearing further British involvement, US President John Tyler decided to secretly enter negotiations with Houston for the annexation of Texas to the United States.
